Description

Technical Field

[0001] This invention relates to the field of tubular belt conveyor technology, and more specifically, to an adjustable steel support structure and adjustment method for a tubular belt conveyor. Background Technology

[0002] Tubular belt conveyors (hereinafter referred to as "tube conveyors") are increasingly widely used in production industries such as coal mine storage and transportation, chemical plants, and power plants due to their advantages of long distance, large capacity, and strong terrain adaptability. Changes in complex terrain are often addressed through steel support structures, which, as important supporting structures of the tube conveyor truss, bear the lateral and vertical loads, wind loads, and seismic effects transmitted by the conveyor, ensuring its smooth operation. Tubular conveyors traverse many areas, encountering some regions with foundations prone to settlement, such as salt-soluble foundations and collapsible foundations. For trusses supported on these foundations, when foundation settlement occurs, the corresponding parts of the truss will also sink and deform, causing the tube conveyor to deviate, become disconnected, or be crushed, resulting in the conveyor malfunctioning. Current measures involve installing various temporary supports and rebuilding the foundation, which are difficult to implement and consume significant manpower and resources.

[0003] Therefore, how to design a steel support structure for a conveyor belt system so that it can compensate for equipment displacement caused by foundation settlement and avoid equipment damage when the foundation settles has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a steel support structure for a conveyor belt machine, so as to compensate for the equipment displacement caused by the foundation settlement by adjusting the steel support structure, thereby avoiding equipment damage.

[0005] Another core aspect of this invention is the disclosure of an adjustment method using the aforementioned steel support structure for a conveyor belt machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustable steel support structure for a conveyor belt machine is provided. The adjustable steel support structure includes a support frame, which comprises alternating fixed-end supports and sliding-end supports. The conveyor belt machine includes a conveyor belt and trusses for supporting the conveyor belt. The trusses comprise at least one set and are arranged among multiple sets of supports. The support frame includes:

[0008] Gantry frame;

[0009] The leveling mechanism is located at the column base of the gantry frame to lift and level the gantry frame.

The column head is mounted on the lifting platform, and its installation position on the lifting platform is adjustable. The support is mounted on the column head, and the truss is mounted on the support. The fixed end support includes a fixed end column head and a fixed support, which are detachably connected. The sliding end support includes a sliding end column head and a sliding support, which are slidably engaged with the sliding end column head.

[0011] Optionally, in the above-mentioned adjustable steel support structure for the conveyor belt, the leveling mechanism includes:

[0014] Auxiliary lifting plate, which is detachably connected to the fixed ring plate;

[0015] The lifting equipment is located below the auxiliary lifting plate;

[0016] Adjustment pads are installed between the fixed plate and the column base;

[0017] Shear keys, including multiple shear keys provided on the column base, each shear key being at least 350mm above the upper surface of the fixed plate.

[0018] Optionally, the above-mentioned adjustable steel support structure for the conveyor belt also includes a lifting device, one end of which is suspended on the gantry and the other end is connected to the lifting platform.

[0019] Optionally, in the above-mentioned adjustable steel support structure for the conveyor belt, a track is provided on the gantry, the lifting platform slides with the track, and a sliding limit component is also provided on the gantry to limit the sliding of the lifting platform.

[0020] Optionally, in the above-mentioned adjustable steel support structure for the conveyor belt machine, the lifting platform is provided with multiple sets of first mounting holes, and the column head is installed and cooperated with the first mounting holes through the first fixing component, so that the installation position of the column head relative to the lifting platform can be adjusted.

[0021] Optionally, in the above-mentioned adjustable steel support structure for the conveyor belt, the support includes multiple supports spaced apart;

[0022] Multiple sets of second mounting holes are provided on the fixed end column head to mate with the fixed support installation;

[0023] Each sliding support is in sliding engagement with the sliding end column head.

[0024] A method for adjusting an adjustable steel support structure for a conveyor belt system, comprising the following steps:

[0025] Determine the degree of settlement of each support;

[0026] For supports with large settlement and tilt, leveling is carried out. The leveling mechanism is used to level each support column of the support so that the observation points of each support column are within the allowable deviation range of the same horizontal plane.

[0027] Adjust the height of the lifting platform, obtain the settlement difference based on the current height of the pipe and the predetermined height, and raise the lifting platform so that the pipe is raised to the predetermined height;

[0028] Adjust the position of the column head on the lifting platform. When the truss shifts horizontally, adjust the relative position of the corresponding column head on the lifting platform to align the pipe belt with the predetermined center line of the pipe belt.

[0029] Adjust the other supports that have settled in turn;

[0030] The overall adjustment effect is measured using measuring instruments. After all the supports that have settled have been adjusted, the overall adjustment effect is measured using measuring instruments.

[0031] Optionally, in the above-mentioned adjustment method for the adjustable steel support structure of the conveyor belt, the step of leveling the support with large settlement and tilt using the leveling mechanism includes:

[0032] Fix the auxiliary lifting plates, and fix each auxiliary lifting plate to the corresponding fixing ring plate;

[0033] Loosen the anchor bolt assembly;

[0034] Arrange the lifting equipment so that the top of each lifting device is pressed tightly against the corresponding auxiliary lifting plate;

[0035] Each lifting device performs lifting operations synchronously until the observation points of each supporting column are within the allowable error range on the same plane.

[0036] Optionally, in the above-mentioned adjustment method for the adjustable steel support structure of the conveyor belt, after the step of leveling the column feet of the support with large settlement and inclination through the leveling mechanism, the following step is also included:

[0037] The lifting equipment should be kept in the lifting state for at least 30 minutes. Observe the compression between the components of the support. If there is no abnormality, insert the adjusting pad according to the space between the fixing plate at the bottom of the support column and the column foot, and then fix the anchor bolt group.

[0038] Optionally, in the above-mentioned adjustment method for the adjustable steel support structure of the conveyor belt, the step of measuring the overall adjustment effect using measuring instruments includes:

[0039] The first measurement is conducted using measuring instruments to confirm the overall lifting and adjustment effect. If the settlement difference is within the allowable range, the lifting equipment and jacking equipment will be unloaded in sequence. If the settlement difference exceeds the allowable range, readjustment will be performed.

[0040] For the second measurement, if the settlement difference from the first measurement is within the allowable range, after the truss has been left to stand still for a period of time under its own weight, a second settlement measurement is performed. If the settlement difference between the two measurements is controlled within the allowable deviation range, the adjustment is complete.

[0041] As can be seen from the above technical solutions, the adjustable steel support structure for the conveyor belt disclosed in this invention can, when foundation settlement occurs, use a leveling mechanism to lift and level the gantry to adjust the inclination of the support; the lifting mechanism can adjust the height of the truss, thereby restoring the height of the conveyor belt to a predetermined height; by adjusting the installation position of the column head on the lifting platform, the horizontal lateral offset of the truss can be adjusted, thereby adjusting the horizontal lateral offset of the conveyor belt; the alternating arrangement of fixed end supports and sliding end supports can release the temperature stress of the truss and reduce the vibration generated during operation; the setting of the sliding end supports allows the truss to slide horizontally and longitudinally, which can adapt to the deformation of the truss caused by foundation settlement.

[0042] The adjustable steel support structure for the conveyor belt disclosed in this invention is simple in structure and easy to adjust. When the foundation settles, it can compensate for the displacement of the conveyor belt caused by the settlement through its own structure, avoiding equipment damage. It can ensure the safe and stable operation of the conveyor belt in settlement areas, effectively solve the problem that the steel support structure of the conveyor belt in settlement areas cannot be reset and adjusted, and reduce the engineering cost of adding steel support structures and raising equipment due to settlement, saving a lot of manpower and material resources.

[0060] The core of this invention is to disclose a steel support structure for a conveyor belt system, which can compensate for equipment displacement caused by foundation settlement by adjusting the steel support structure during foundation settlement, thereby avoiding equipment damage.

[0061] Another core aspect of this invention is the disclosure of an adjustment method using the aforementioned steel support structure for a conveyor belt machine.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] like Figure 1 As shown in the figure, an adjustable steel support structure for a conveyor belt machine is disclosed in this embodiment of the invention, including a support 100, which includes a gantry frame 110, a leveling mechanism 130 and a lifting mechanism 120.

[0064] The conveyor belt 200 includes a conveyor belt 210 and a truss 220 for supporting the conveyor belt 210. The conveyor belt 210 includes a first tubular conveyor belt and a second tubular conveyor belt. One of them is used for the carrying section and the other is used for the return section. The first tubular conveyor belt and the second tubular conveyor belt can be arranged vertically or horizontally. The figure shows an example of vertical arrangement.

[0065] The support frame 100 includes alternating fixed-end supports and sliding-end supports, with at least one set of fixed-end supports and one set of sliding-end supports. The truss 220 includes at least one set, and the truss 220 is arranged among multiple sets of supports 100, with the supports 100 providing support for the truss 220. The figure shows two sets of supports 100, one set being fixed-end supports and the other being sliding-end supports. The truss 220 is arranged in one set, with one end detachably connected to the fixed-end support and the other end slidingly engaged with the sliding-end support. That is, one end of the truss 220 is fixed, and the other end is limited, preventing deformation or breakage of the truss 220 due to expansion, deformation, vibration, or other factors.

[0066] The support frame 100 includes a gantry frame 110, a leveling mechanism 130, and a lifting mechanism 120. The leveling mechanism 130 is located at the bottom column foot 140 of the gantry frame 110. When foundation settlement occurs and the support frame 100 tilts, the leveling mechanism 130 can lift and level the gantry frame 110 to keep it in a horizontal state.

[0067] like Figure 2 and Figure 3 As shown, the lifting mechanism 120 includes a lifting platform 121, a column head, and a support. Specifically, the lifting platform 121 is slidably mounted on the gantry frame 110, the column head is mounted on the lifting platform 121, the support is mounted on the column head, and the truss 220 is mounted on the support. The support is used to bear the vertical load and longitudinal seismic effects transmitted from the upper conveyor belt 210. The fixed-end support includes a fixed-end column head 122 and a fixed support 125, which are detachably connected. The sliding-end support includes a sliding-end column head 123 and a sliding support 126, which are slidably engaged with the sliding-end column head 123.

[0068] The lifting platform 121 is slidably mounted on the gantry frame 110, enabling the lifting platform 121 to move vertically (i.e., Figure 1 The pipe 210 can slide up and down in the Z direction (as shown in the diagram), thereby driving the truss 220 to move up and down, and in turn driving the pipe 210 to move up and down. When foundation settlement occurs, the vertical height of the pipe 210 can be adjusted according to the degree of settlement.

[0069] The installation position of the column head on the lifting platform 121 can be adjusted, which here refers to the direction perpendicular to the running direction of the hose 210 (i.e., Figure 1 The installation position (shown in the X direction) can be adjusted so that when foundation settlement occurs, the truss 220 will move horizontally (perpendicular to the running direction of the pipe belt 210, i.e.) Figure 1 When the offset is in the X direction (as shown), the offset of the truss 220 can be adjusted by adjusting the installation position of the column head on the lifting platform 121, so that the truss 220 is adjusted to the predetermined center line of the pipe belt 210, thereby adjusting the position of the pipe belt 210.

[0070] The adjustable steel support structure for the conveyor belt disclosed in this invention allows the leveling mechanism 130 to lift and level the gantry 110 during foundation settlement, thereby adjusting the tilt of the support 100. The lifting mechanism 120 adjusts the height of the truss 220, restoring the height of the conveyor belt 210 to a predetermined height. Adjusting the installation position of the column head on the lifting platform 121 adjusts the horizontal lateral offset of the truss 220, thus adjusting the horizontal lateral offset of the conveyor belt 210. The alternating arrangement of fixed-end and sliding-end supports releases the temperature stress of the truss 220 and reduces vibration during operation. The sliding-end support allows the truss 220 to move horizontally (parallel to the direction of travel of the conveyor belt 210, i.e.,...) Figure 1 The sliding (in the Y direction shown) can accommodate the deformation of truss 220 caused by foundation settlement.

[0071] It should be noted that there are several ways to achieve lifting and lowering by sliding cooperation between the lifting platform 121 and the gantry frame 110. Specifically, the lifting platform 121 can be raised and lowered by setting a screw, which is rotatably connected to the gantry frame 110 and threadedly connected to the lifting platform 121. By rotating the screw, the lifting platform 121 can slide up and down along the vertical direction of the gantry frame 110. Alternatively, the lifting platform 121 can be slid up and down along the gantry frame 110 by setting a drive cylinder. The fixed end of the drive cylinder can be set on the gantry frame 110, and the piston rod is connected to the lifting platform 121. The up and down sliding of the lifting platform 121 is achieved by the extension and retraction of the piston rod. Alternatively, a telescopic rod can be set. The fixed end of the telescopic rod can be set on the gantry frame 110, and the telescopic end is connected to the lifting platform 121. The up and down sliding of the lifting platform 121 along the gantry frame 110 is achieved by the extension and retraction of the telescopic rod. Alternatively, hoisting equipment can be used to hoist the lifting platform 121 and slide it up and down along the gantry frame 110. The specific method is not limited.

[0072] The installation position of the column head and the lifting platform 121 can be adjusted. Specifically, it can be achieved by sliding the column head and the lifting platform 121 together, or by adjusting the position of the mounting parts of the column head and the lifting platform 121, or by combining the two methods. The specific method is not limited.

[0073] The adjustable steel support structure for the conveyor belt disclosed in this invention is simple in structure and easy to adjust. When the foundation settles, it can compensate for the displacement of the conveyor belt 200 caused by the settlement through its own structure, avoiding equipment damage. It can ensure the safe and stable operation of the conveyor belt 200 in settlement areas, effectively solve the problem that the steel support structure of the conveyor belt 200 cannot be reset and adjusted in settlement areas, and reduce the engineering cost of supplementing the steel support structure and raising the equipment due to settlement, saving a lot of manpower and material resources.

[0074] like Figure 2 and Figure 3 As shown, in some specific embodiments, the gantry 110 includes at least four supporting columns 1101, preferably four supporting columns 1101. The supporting columns 1101 can be round tubes or square tubes, preferably round tubes. Each supporting column 1101 is connected by a fixed frame 1102, which ensures the stability of the gantry 110 structure. To further improve the structural stability, the tops of two supporting columns 1101 arranged along the horizontal longitudinal direction (parallel to the running direction of the conveyor belt 210) are connected by a longitudinal beam.

[0075] like Figures 8-9As shown, in some specific embodiments, the leveling mechanism 130 includes a fixed ring plate 131, anchor bolts 132, an auxiliary lifting plate 133, adjusting pads 134, a lifting device 135, and a shear key 136. The fixed ring plate 131 includes at least two plates, with multiple fixed ring plates 131 disposed at the bottom of the support column 1101 of the bracket 100 and arranged circumferentially along the support column 1101. When the number of fixed ring plates 131 is two, the two fixed ring plates 131 are preferably arranged symmetrically along the axis of the support column 1101. Preferably, the number of fixed ring plates 131 is four, and the four fixed ring plates 131 are arranged symmetrically along the axis of the support column 1101.

[0076] Anchor bolts 132 include a plurality of bolts arranged circumferentially along the support column 1101. A fixing plate 112 is provided at the bottom of the support column 1101. The fixing plate 112 is connected to the column base 140 by a plurality of anchor bolts 132. Shear keys 136 are provided on the column base 140. Shear keys 136 include a plurality of bolts 136. To prevent the support 100 and the column base 140 from becoming dislodged during leveling of the bracket 100, each anchor bolt 132 and shear key 136 extends at least 350 mm above the upper surface of the fixing plate 112. The auxiliary lifting plate 133 is detachably connected to the fixing ring plate 131, specifically by means of bolts and nuts. This connection method is convenient for disassembly and assembly. The specific number of auxiliary lifting plates 133 corresponds to the number of fixing ring plates 131. The lifting device 135 is positioned below the auxiliary lifting plate 133. It levels the bracket 100 by tightening the auxiliary lifting plate 133. The lifting device 135 and the auxiliary lifting plate 133 can be paired one-to-one, or two can be used. Specifically, the lifting device 135 can be a jack or a telescopic cylinder. Adjusting shims 134 are positioned between the fixed plate 112 and the column base 140. The specific number of adjusting shims 134 is selected according to the actual leveling requirements.

[0077] Taking the jacking device 135 as an example, when the terrain settles, the support 100 tilts, and the leveling mechanism 130 levels the support 100. Specifically, first, each auxiliary jacking plate 133 is fixed to the fixing ring plate 131 on the side of the column base 140 that has sunk, then the corresponding anchor bolts 132 are loosened, and then the jacks are placed on the laid sleepers (the sleepers are located on the column base 140), so that the jacks tighten the auxiliary jacking plates 133. Taking two jacks as an example, during jacking, the two jacks should be operated synchronously, for example, by gradually jacking and leveling in 10mm increments, preferably with a maximum jacking height not exceeding 350mm. When the jacking force is about to reach the constant load of the support 100, the jacking should be slowed down so that the height difference of the observation points 1103 on each support column 1101 is controlled within the allowable deviation range of the same horizontal plane. To facilitate leveling, observation points 1103 are set on each support column 1101 of the bracket 100. After leveling and stabilization, a corresponding number of adjusting shims 134 are inserted according to the space between the leveled fixing plate 112 and the column base 140. Finally, all anchor bolts 132 are fixed to ensure the stability of the bracket 100 after leveling. After the bracket 100 is stabilized, the lifting device 135 can be removed.

[0078] The leveling mechanism 130 disclosed in this embodiment of the invention has a simple structure, is easy to level, and is convenient to operate. The lifting device 135 does not need to be fixed on the column base 140 and can be reused.

[0079] In some specific embodiments, such as Figure 2 and Figure 3 As shown, the adjustable steel support structure of the conveyor belt also includes a lifting device 124. One end of the lifting device 124 is suspended on the gantry frame 110, and the other end is connected to the lifting platform 121. Specifically, the gantry frame 110 has a first lifting hole 1104 for suspending the lifting device 124, which can be located on the longitudinal beam. The lifting platform 121 has a second lifting hole 1212 for suspending the lifting device 124, so as to provide a pulling function when it is necessary to slide the lifting platform 121 vertically up and down along the gantry frame 110. Specifically, the lifting device 124 can be a manual hoist, an electric hoist, or a pulley system, with a manual hoist or an electric hoist being preferred.

[0080] like Figure 2 and Figure 3As shown, a vertically extending track 111 is provided on the gantry frame 110. The lifting platform 121 slides with the track 111. To limit the sliding of the lifting platform 121, a limiting component is also provided on the gantry frame 110. In some specific embodiments, multiple third mounting holes 1111 are evenly provided on the track 111 along its extension direction. The lifting platform 121 slides with the track 111 via a sliding member 127. The sliding member 127 is installed with the third mounting holes 1111 via a third fixing member, thereby limiting the lifting platform 121. The distance between two adjacent third mounting holes 1111 is not specifically limited and can be set to 150mm or other values. The multiple third mounting holes 1111 allow for stepped adjustment of the lifting platform 121, making the adjustment more precise. Those skilled in the art will understand that other solutions can also be used for the limiting component.

[0081] The lifting platform 121 is a frame structure with an overall rectangular layout, which can be welded from H-beams. In order to enable better sliding cooperation between the lifting platform 121 and the gantry frame 110, at least two sets of vertically arranged rails 111 are provided on each support column 1101. The rails 111 can be long plates and can be fixed to the support column 1101 by welding.

[0082] The figure shows that each supporting column 1101 has two tracks 111, allowing the side beams around the lifting platform 121 to slide in conjunction with the tracks 111. In some specific embodiments, such as... Figures 3-5 As shown, the sliding component 127 is made of steel plate. Two steel plates are set at the position where each side beam mates with the rail 111. The steel plates are connected to the rail 111 and the side beam by bolts and nuts respectively. The steel plates can also play a limiting and fixing role during the lifting process.

[0083] During normal operation of the conveyor belt 200, the lifting platform 121 is secured to the gantry frame 110 via a third fixing member that engages with the third mounting hole 1111. The third fixing member can be bolts and nuts. At this time, the lifting device 124 may or may not be suspended from the gantry frame 110, but it is connected to the lifting platform 121 and is under tension to ensure the secure connection between the lifting platform 121 and the gantry frame 110. The lifting device 124 not only provides the power for lifting the lifting platform 121 but also ensures the stability of the lifting platform 121 during the lifting process. After the lifting platform 121 is raised to a preset distance and secured, the lifting device 124 can be removed and reused.

[0084] When the height of the truss 220 needs to be adjusted due to foundation settlement, one end of the lifting equipment 124 is suspended on the gantry 110 and the other end is fixed on the lifting platform 121. The lifting equipment 124 is tightened to maintain the overall stability of the lifting platform 121. Then, the third fixing component is removed, and the lifting platform 121 is made to slide vertically along the track 111 on the gantry 110 by means of the lifting equipment 124. After adjusting to the predetermined height for the operation of the hose 210, the lifting platform is fixed to the gantry 110 by means of the third fixing component.

[0085] like Figures 2-3 As shown, in order to adjust the installation position of the column head on the lifting platform 121, in some specific embodiments, the lifting platform 121 is provided with multiple sets of first mounting holes 1211 arranged horizontally. Each set of first mounting holes 1211 includes two arranged horizontally, and the distance between two adjacent sets of first mounting holes 1211 can be 200mm. The column head is installed and engaged with the first mounting hole 1211 by a first fixing member. When the foundation settles and the truss 220 shifts, the first fixing member is first removed, and the column head is pulled horizontally by equipment to adjust the hose 210 to the predetermined position. Then, the first fixing member is installed and engaged with the corresponding first mounting hole 1211. The first fixing member can be a bolt or nut. The equipment used here can be lifting equipment 124. Specifically, a second lifting hole 1212 is provided on the side beam arranged horizontally and longitudinally on the lifting platform 121, and a third lifting hole 1224 is provided on the column head. One end of the lifting equipment 124 can be connected to the second lifting hole 1212, and the other end can be connected to the third lifting hole 1224. After the lifting platform 121 reaches the predetermined position, the column head and the lifting platform 121 can be fixed by the first fixing component. The lifting equipment 124 here can be the one suspended between the gantry 110 and the lifting platform 121. The lifting equipment 124 can be recycled, which can reduce costs. This method is convenient to operate.

[0086] like Figures 6-7 As shown, in some specific embodiments, the column head is a frame structure, which can be welded together from five H-beams. Four of the H-beams form the four sides of the rectangular structure, and the other H-beam is placed in the middle of the column head and connects the two H-beams arranged along the length direction to provide reinforcement.

[0087] The adjustable steel support structure for the conveyor belt disclosed in this invention includes multiple supports spaced apart. Figure 6The diagram shows the structure of the fixed end column head 122. The fixed end column head 122 includes a shoulder beam 1221 and a fixed support 125 mounted on it. The shoulder beam 1221 has multiple sets of second mounting holes 1233 that mate with the fixed support 125. The fixed support 125 is detachably connected to the second mounting holes 1233 via second fasteners. The multiple sets of second mounting holes 1233 are arranged horizontally and longitudinally so that when the truss 220 moves along the running direction of the pipe belt 210, the installation position of the fixed support 125 on the fixed end column head 122 can be adjusted to accommodate the movement of the truss 220.

[0088] Figure 7 The diagram shows the structure of the sliding end column head 123. The sliding end column head 123 includes a track beam 1231, and sliding supports 126 that slide in conjunction with the track beam 1231. Specifically, a sliding plate 1232, which can be made of polytetrafluoroethylene (PTFE), is provided on the track beam 1231. Two PTFE plates are respectively positioned on the track beam 1231 arranged in the horizontal longitudinal direction. Each sliding support 126 slides in conjunction with the sliding plate 1232. A sliding support limiting member 1261 is provided on the sliding support 126, which can be limited along the extension direction of the track beam 1231 by setting an L-shaped buckle at the bottom of the sliding support 126. The lengths of the two side beams arranged in the horizontal transverse direction of the sliding end column head 123 extend beyond the track beam 1231 arranged in the horizontal longitudinal direction to limit the sliding of the sliding supports 126 and prevent the sliding supports 126 from detaching from the sliding end column head 123. To ensure the stability of the support for truss 220, the number of fixed supports 125 and sliding supports 126 shall be at least two. As shown in the figure, the number of fixed supports 125 and sliding supports 126 are four.

[0089] In order to monitor the settlement of the foundation, the adjustable steel support structure of the conveyor belt disclosed in this embodiment of the invention also includes a settlement monitoring mechanism. The settlement monitoring mechanism can be installed on the gantry 110 to monitor the settlement of the foundation, so as to facilitate the staff to obtain the settlement information of the foundation more quickly.

[0090] Furthermore, this invention also discloses an adjustment method for an adjustable steel support structure for a conveyor belt system, employing the adjustable steel support structure for a conveyor belt system disclosed in the above embodiments, comprising the following steps:

[0091] S1. Determine the degree of settlement of each support 100;

[0092] After the foundation settlement occurred, the staff checked the installation of the support 100 and the settlement range of each support 100, and verified the elevation of the column base 140 and the lifting platform 121.

[0093] S2. Level the support 100 with large settlement and tilt.

[0094] The leveling mechanism 130 is used to level each support column 1101 of the support 100 to adjust the tilt of the support 100 during foundation settlement, so that the observation points 1103 of each support column 1101 are within the allowable deviation range of the same horizontal plane.

[0095] Specifically, the steps include the following:

[0096] S21, Fixed auxiliary lifting plate 133;

[0097] Each auxiliary lifting plate 133 is fixed to its corresponding fixing ring plate 131.

[0098] S22, Loosen all anchor bolts 132;

[0099] S23, Arrange 135 lifting equipment;

[0100] Pillars are arranged on each column base 140, and jacking devices 135 are arranged on the pillars, so that the top of each jacking device 135 is pressed against the corresponding auxiliary jacking plate 133.

[0101] S24, All lifting devices 135 perform lifting operations simultaneously;

[0102] To ensure that each lifting device 135 operates synchronously and gradually, it is preferable to lift in increments of 10mm, with a maximum lifting height not exceeding 350mm. When the lifting force is about to reach the constant load of the upper support 100, the lifting should be slowed down so that the height difference of the four observation points 1103 is controlled within the allowable deviation range on the same horizontal plane.

[0103] S3. Adjust the height of the lifting platform 121;

[0104] Based on the settlement difference between the current height and the predetermined height of the hose 210, the lifting platform 121 is raised to elevate the hose 210 to the predetermined height. Specifically, the third fixing component is removed, and the lifting platform 121 is raised to the predetermined height by the lifting equipment 124. Then, the sliding component 127 and the track 111 are fixed by the third fixing component to complete the height adjustment of the lifting platform 121.

[0105] S4. Adjust the position of the column head on the lifting platform 121;

[0106] When the truss 220 shifts laterally in the horizontal direction, the installation position of the corresponding column head on the lifting platform 121 is adjusted to bring the hose 210 to its predetermined position. Specifically, this involves disassembling the first fixing member, then using the lifting equipment 124 to pull the column head along the lifting platform 121 in the horizontal direction. After the column head is adjusted to the predetermined position, the first fixing member is installed and engaged with the corresponding first mounting hole 1211.

[0107] S5. Adjust the other supports that have settled in sequence;

[0108] Repeat steps S2-S4 to adjust the other supports 100 that have settled in turn.

[0109] S6. Measure the overall adjustment effect using measuring instruments;

[0110] After all the supports 100 that have settled have been adjusted, the overall adjustment effect is measured using measuring instruments. If any support 100 does not meet the requirements, it is readjusted and then measured again.

[0111] Based on the above embodiments, the following step is included after step S2:

[0112] S2', The lifting device 135 maintains the lifting state for at least thirty minutes, and observes the compression between the components of the support 100;

[0113] It is preferable to maintain the jacking state for 30 minutes and observe the compression between the components of the support 100. If there is no abnormality, insert the corresponding number of adjusting pads 134 according to the space between the fixing plate at the bottom of the support column 1101 and the column foot 140. Then fix the anchor bolts 132 to ensure the stability of the support 100 during subsequent adjustments. If there is any abnormality, stop working immediately.

[0114] The adjustment method for the adjustable steel support structure of the conveyor belt disclosed in this embodiment of the invention specifically includes step S6:

[0115] S61, First measurement;

[0116] The first measurement is conducted using measuring instruments to confirm the overall lifting and adjustment effect. If the settlement difference is within the allowable range, the lifting equipment 124 and the jacking equipment 135 are unloaded in sequence. If the settlement difference exceeds the allowable range, the adjustment is readjusted.

[0117] S62, Second measurement;

[0118] If the settlement difference measured in the first measurement is within the allowable range, after the truss 220 has been left to stand for a preset time under its own weight, a second measurement is performed. If the settlement difference between the two measurements is controlled within the allowable deviation range, the adjustment is complete.

[0119] For ease of explanation, the overall settlement adjustment amplitude is defined as L, which is jointly determined by the lifting value L1 of the lifting platform 121, the leveling value L2 of the column base 140, and the horizontal tilt value L3. Figure 10As shown. When the lifting value L1 and horizontal tilt value L3 of the lifting platform 121 remain unchanged, only the leveling value L2 of the column base 140 needs to be adjusted, and the maximum leveling height of the leveling device L2 of the column base 140 does not exceed 350mm; when the leveling value L2 and horizontal tilt value L3 of the column base 140 remain unchanged, only the lifting value L1 of the lifting platform 121 needs to be adjusted, and the maximum lifting height of the lifting platform 121 L1 does not exceed 5m; when the lifting value L1 of the lifting platform 121 and the leveling value L2 of the column base 140 remain unchanged, only the horizontal tilt value L3 needs to be adjusted, and the maximum offset width of the truss 220 on the lifting platform 121 does not exceed 1m. When the lifting value L1 of the lifting platform 121, the leveling value L2 of the column base 140, and the horizontal tilt value L3 change simultaneously, the leveling value L2 of the column base 140, the horizontal tilt value L3, and the lifting value L1 of the lifting platform 121 are adjusted sequentially in space.
