Description

Technical Field

[0001] This utility model relates to the field of conveyor adjustment technology, and in particular to an adjustment frame and a support that can be laterally slidably adjusted. Background Technology

[0002] Coal mine belt conveyors are the core equipment for underground coal transportation. They achieve efficient and continuous coal transportation through components such as conveyor belts, drive devices, and support structures. They are capable of long-distance transportation and adapting to complex environments, and are widely used in underground coal transportation.

[0003] The H-frame, which is a bracket used to fix the idlers and support the belt, is the main support structure of the belt conveyor. To accommodate the relocation of the working face and adapt to different inclination angles of the roadway, multiple workers are required to move and calibrate the H-frame during the installation of the belt conveyor, especially when calibrating the belt conveyor for straightness. This results in high labor intensity and low installation efficiency.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to solve the problem of difficulty in moving and calibrating the device while ensuring the stability of the H-frame support.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model claims a protective adjustment frame, including a first adjustment plate, a first fixed rod, a second fixed rod, a second adjustment plate, a transfer unit, and a locking unit. The first adjustment plate and the second adjustment plate are transferred through the transfer unit. One end of the first fixed rod is provided on the first adjustment plate. The suspended end of the first fixed rod extends towards the second adjustment plate. The second adjustment plate is connected to one end of the second fixed rod. The first adjustment plate and the second adjustment plate are flipped so that the suspended end of the second fixed rod is connected to the suspended end of the first fixed rod through the locking unit. The first adjustment plate and the second adjustment plate are fixed to each other.

[0008] By setting up a transfer unit, the first adjustment plate and the second adjustment plate can be transferred to each other. On this basis, a locking unit is set up to lock the plate after the transfer, so that the first adjustment plate and the second adjustment plate can switch between rotating and fixed states.

[0009] Preferably, the adapter unit includes a first rotating ear, a second rotating ear, and a pin. The first rotating ear is provided on the wide side of the first adjusting plate, and the second rotating ear is provided on the wide side of the second adjusting plate. The second rotating ear and the first rotating ear are staggered from each other, and the second rotating ear and the first rotating ear pass through through holes aligned with each other. The axis of the through holes is parallel to the wide side of the first adjusting plate, and the pin is coaxially inserted into the through holes.

[0010] The staggered positions of the second and first rotating ears ensure that the first and second adjusting plates do not interfere with each other during rotation.

[0011] Preferably, the first fixing rod includes at least two rods, which are respectively placed on both sides of the first adjusting plate. The side of the first adjusting plate is connected to one end of the corresponding first fixing rod, and the other end of the first fixing rod constitutes the suspension end of the first fixing rod. The second fixing rod includes at least two rods, which are respectively placed on both sides of the second adjusting plate. The side of the second adjusting plate is connected to one end of the second fixing rod by a pin. The second fixing rod is located between at least two first fixing rods, and the other end of the second fixing rod constitutes the suspension end of the second fixing rod.

[0012] Setting at least two first and second fixing rods can ensure that the second adjusting plate and the first adjusting plate are subjected to force evenly, thus preventing tilting.

[0013] Preferably, the locking unit includes a socket and a pin, with the first fixing rod suspension end and the second fixing rod suspension end passing through the socket, and the pin being coaxially inserted into the socket.

[0014] The pin is coaxially inserted into the socket to fix the first and second adjustment plates.

[0015] Preferably, the width of the first adjusting plate is smaller than the width of the second adjusting plate.

[0016] When the first adjusting plate and the second adjusting plate are rotated to fit together, the second adjusting plate is located within the space enclosed by the first adjusting plate and the first fixed rod, thus avoiding interference between them.

[0017] Preferably, the distance from the first fixing rod to the pin is equal to the distance from the second fixing rod to the pin.

[0018] The distance from the first fixing rod to the pin is equal to the distance from the second fixing rod to the pin, which ensures that the suspension ends of the first fixing rod and the second fixing rod coincide as much as possible.

[0019] Preferably, the first fixing rod and the surface of the first adjusting plate form a first included angle of 45°.

[0020] The first included angle is 45°, so that the second fixed rod and the first fixed rod form a support and fixation between the first adjustment plate and the second adjustment plate. When the first fixed rod and the second fixed rod rotate to 90° with each other, they are on the same straight line, which means that the second fixed rod, the first fixed rod, the second adjustment plate and the first adjustment plate form a stable triangular structure, which makes the fixation of the first adjustment plate and the second adjustment plate more stable.

[0021] This utility model claims protection for a horizontally sliding and tiltable bracket, including an adjustment frame, a bracket body, and a rolling element, wherein the rolling element is mounted on the bottom side of the bracket body via the adjustment frame.

[0022] The adjusting bracket allows the rolling element to switch between tilting and stationary movement.

[0023] Preferably, a first adjusting plate is provided on the bottom side of the support body, and a rolling element is provided on the surface of a second adjusting plate away from the first adjusting plate.

[0024] The connection between the bottom side of the bracket body and the first adjustment plate can be either detachable or welded.

[0025] Preferably, the rolling element is a universal roller.

[0026] The omnidirectional casters offer high flexibility in adjustment, making them easy for personnel to operate. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Example 1

[0038] See Figure 1 and Figure 2 This embodiment requires a protective adjustment frame, including a first adjustment plate 11, a first fixing rod, a second fixing rod, a second adjustment plate 14, a connecting unit 15, and a locking unit. The first adjustment plate 11 and the second adjustment plate 14 are connected to each other via the connecting unit 15. Specifically, the connecting unit 15 includes a first rotating ear 150, a second rotating ear 151, and a pin 152. Both the first adjustment plate 11 and the second adjustment plate 14 are flat. The first adjustment plate 11 has a first rotating ear 150 protruding from its wide side, which passes through a first through hole. The axis of the first through hole is parallel to the wide side of the first adjustment plate 11. The second adjustment plate 14 has a second rotating ear 151 protruding from its wide side, which passes through a second through hole. The axis of the second through hole is parallel to the wide side of the second adjustment plate 14. The second rotating ear 151 and the first rotating ear 150 are staggered. The pin 152 is coaxially inserted into the first through hole and the second through hole.

[0039] The second rotating ear 151 and the first rotating ear 150 are staggered in position, meaning that when the first adjusting plate 11 and the second adjusting plate 14 are aligned with each other along their wide sides, the second rotating ear 151 and the first rotating ear 150 are staggered with each other along their wide sides, and the first through hole and the second through hole are arranged coaxially. Preferably, the first rotating ear 150 is provided in the middle of the wide side of the first adjusting plate 11, and the second pole ears are provided on both sides of the wide side of the second adjusting plate 14. A gap is left between the second pole ears to accommodate the first rotating ear 150. When the first adjusting plate 11 and the second adjusting plate 14 are aligned with each other along their wide sides, the first rotating ear 150 is placed in the gap left between the second pole ears.

[0040] The first adjusting plate 11 has one end of the first fixing rod, and the suspended end of the first fixing rod extends towards the second adjusting plate 14. The second adjusting plate 14 is connected to one end of the second fixing rod. The first adjusting plate 11 and the second adjusting plate 14 are flipped so that the suspended end of the second fixing rod is connected to the suspended end of the first fixing rod through a locking unit, thus fixing the first adjusting plate 11 and the second adjusting plate 14 to each other. Specifically, the locking unit includes a pin 160 and a socket. The side of the first adjusting plate 11 is connected to one end of the first fixing rod, and the other end of the first fixing rod forms the suspended end of the first fixing rod. The side of the second adjusting plate 14 is connected to one end of the second fixing rod, and the other end of the second fixing rod forms the suspended end of the second fixing rod. Both the suspended ends of the first and second fixing rods pass through the socket, and the pin 160 is coaxially inserted into the socket, thereby fixing the first adjusting plate 11 and the second adjusting plate 14.

[0041] The number of first fixing rods is not limited. In actual operation, two first fixing rods are preferred: a first left fixing rod 12a and a first right fixing rod 12b, which are respectively located on both sides of the first adjusting plate 11. Similarly, two second fixing rods are preferred: a second left fixing rod 13a and a second right fixing rod 13b, which are respectively connected to both sides of the second adjusting plate 14 by pins. The second fixing rods are located between at least two first fixing rods. Pins 160 pass through the insertion holes on the first left fixing rod 12a, the second left fixing rod 13a, the first right fixing rod 12b, and the second right fixing rod 13b in sequence to fix the first adjusting plate 11 and the second adjusting plate 14. The advantage of this arrangement is that the force is more evenly distributed, preventing the first adjusting plate 11 and the second adjusting plate 14 from shifting or deforming.

[0042] The second fixing rod being located between at least two first fixing rods means that, in order to ensure that the first adjusting plate 11 and the second adjusting plate 14 do not interfere with each other when they rotate, the width of the first adjusting plate 11 is preferably greater than the width of the second adjusting plate 14. When the first adjusting plate 11 and the second adjusting plate 14 rotate to fit together, the second adjusting plate 14 is located within the space enclosed by the first adjusting plate 11 and the first fixing rod.

[0043] Furthermore, to ensure that the sockets can align with each other, preferably, the distance from the first fixing rod to the pin 152 is equal to the distance from the second fixing rod to the pin 152. When the distances from the first fixing rod to the pin 152 and the second fixing rod to the pin 152 are equal, it can be ensured that the suspension ends of the first fixing rod and the suspension ends of the second fixing rod coincide as much as possible.

[0044] Furthermore, by forming a first angle of 45° between the first fixed rod and the surface of the first adjusting plate 11, the first fixed rod and the second fixed rod are aligned on the same straight line when the first adjusting plate 11 and the second adjusting plate 14 are rotated to 90° with each other. This means that the second fixed rod, the first fixed rod, the second adjusting plate 14 and the first adjusting plate 11 form a stable triangular structure for support, which makes the fixation of the first adjusting plate 11 and the second adjusting plate 14 more stable.

[0045] See Figure 3 It is worth noting that since the second fixing rod and the second adjusting plate 14 are connected by a pin, fixing the first adjusting plate 11 and the second adjusting plate 14 also includes rotating the second fixing rod to coincide with the long side of the second adjusting plate 14, and then rotating the second adjusting plate 14 so that the second adjusting plate 14 is close to the first adjusting plate 11. At this time, the first fixing rod extends to the side of the second adjusting plate 14 away from the first adjusting plate 11, and then the pin 160 is inserted into the socket to fix and retract the first adjusting plate 11 and the second adjusting plate 14.

[0046] Example 2

[0047] See Figure 4 and Figure 5 This embodiment requires protection of a laterally sliding and tiltable support, including an adjustment frame, a support body 2, and rolling elements 3. The rolling elements 3 are mounted on the bottom side of the support body 2 via the adjustment frame. Specifically, a first adjustment plate 11 is provided on the bottom side of the support body 2, and the rolling elements 3 are mounted on the surface of a second adjustment plate 14 away from the first adjustment plate 11. The rolling elements 3 are universal rollers, preferably universal rollers with a brake plate 34. The support includes a connecting frame 30, a steering shaft 31, a brake bolt 32, rollers 33, and a brake plate 34. The connecting frame 30 connects to the rollers 33 via the steering shaft 31. The connecting frame 30 is preferably manufactured using a one-piece stamping process, providing certain protective and support functions. The brake plate 34 is connected to the connecting frame 30 via the brake bolt 32. The rollers 33 are preferably made of EPDM rubber, possessing heat resistance and electrical insulation properties, and are adaptable to complex environments. In use, the brake plate 34 can be activated by manually pressing or stepping on it; this is existing technology and will not be described in detail.

[0048] The connection between the bottom side of the bracket body 2 and the first adjusting plate 11 can be a detachable connection or a welded connection, depending on the actual working conditions. When it is a detachable connection, bolts are preferred. Specifically, four mounting holes are evenly opened on the first adjusting plate 11, and the corresponding bolts pass through the mounting holes and engage with the threaded holes opened on the bottom side of the bracket body 2.

[0049] Similarly, the connection between the connecting frame 30 and the second adjusting plate 14 can also be welded or detached. When it is detached, refer to the connection between the bracket body 2 and the first adjusting plate 11, and will not be described again.

[0050] This document provides specific application scenarios for the laterally sliding and tilt-adjustable support, specifically for tilt adjustment during the straight-line calibration of a coal mine belt conveyor. The process of using this laterally sliding and tilt-adjustable support for tilt adjustment is as follows:

[0051] When the bracket needs to be moved, pull out the pin 160, rotate the second adjusting plate 14 so that the second adjusting plate 14 is at 90° to the bracket, rotate the second left fixing rod 13a and the second right fixing rod 13b so that the second left fixing rod 13a is in a straight line with the first left fixing rod 12a. At this time, the second fixing rod, the first fixing rod, the second adjusting plate 14 and the first adjusting plate 11 form a stable triangular structure. Insert the pin 160 coaxially into the socket to fix the first adjusting plate 11 and the second adjusting plate 14. At this time, the casters face the bottom surface, and the bracket can be tilted by pushing. When multiple brackets move at the same time, the brake plate 34 is used to brake and lock the bracket that has been tilted and calibrated. Then, the multiple brackets are tilted in turn.

[0052] When the bracket does not need to be moved, pull out the pin 160, rotate the second fixing rod until it coincides with the long side of the second adjusting plate 14, and then rotate the second adjusting plate 14 so that the second adjusting plate 14 is close to the first adjusting plate 11. At this time, the first fixing rod extends to the side of the second adjusting plate 14 away from the first adjusting plate 11. Then insert the pin 160 into the socket. At this time, the pin 160 and the caster are misaligned, thus fixing the first adjusting plate 11 and the second adjusting plate 14. At this time, the caster is flipped to the side of the bracket and no longer plays a role in moving or tilting the bracket.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
