Description
Technical Field
[0001] This utility model relates to the field of idler roller replacement, and in particular to a tooling for replacing idler rollers of a belt conveyor. Background Technology
[0002] Belt conveyors typically include a belt and idlers. The idlers are mounted on a trough idler frame, which includes a horizontally arranged crossbeam. Support rods are mounted at both ends of the crossbeam. The support rods have a bent structure. Two supports are symmetrically arranged in the middle of the crossbeam. Three idlers are rotatably mounted sequentially between the support rod and the support at one end, between the two supports, and between the support and the support rod at the other end.
[0003] In the prior art, Chinese invention patent application publication number CN108723730A discloses a tooling for changing idler rollers of a belt conveyor. The tooling includes at least: a base, a lifting mechanism, a support member, two upper supports, and two adjusting members. The lower end of the lifting mechanism is mounted on the base, and the upper end is connected to the support member. The lifting mechanism can raise or lower the support member. One end of each of the two upper supports is hinged to the support member, and the other end is a free end located above the two ends of the support member. The two ends of one adjusting member are respectively connected to the support member and one... One upper support component is connected to the other upper support component, and the two ends of the other adjusting component are respectively connected to the support component and the other upper support component. By adjusting the connection positions of the two ends of the two adjusting components with the support component and the upper support component, the height at which the free end of the upper support component is raised relative to the support component can be adjusted. In use, the upper support component can be raised by driving the lifting mechanism to adjust the height of the free end of the upper support component. After the upper support component supports the belt and moves upward, the idler roller that needs to be replaced can be replaced. After replacement, the lifting mechanism can be driven to descend and return to its original position. The operation is convenient and can be completed quickly, which can reduce labor intensity and improve work efficiency.
[0004] When using the above technical solutions, the base needs to be placed on the bottom plate of the conveyor belt. When the height of the bottom plate and the conveyor belt exceeds the travel of the lifting mechanism, stones or wood need to be placed under the base as pads to raise the height of the base. Moreover, stones or wood are usually sourced locally on site, and their levelness is poor, so they cannot stably support the base. Special pads also need to be provided. It can be seen that the above technical solutions have a limited scope of application and are not flexible in use. Utility Model Content
[0005] To address the technical problems of insufficient travel and inflexible use of existing idler roller replacement fixtures, this invention provides a fixture for replacing belt conveyor idler rollers that can be directly installed on a trough-type idler roller frame, thus avoiding insufficient lifting travel.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a tooling for replacing belt conveyor idlers, including a support member, and further including: a mounting base, the mounting base including a bearing member, a limiting plate and a fastening plate, the limiting plate being connected to the bearing member, the limiting plate being able to abut against the crossbeam of the trough idler frame, the bearing member being located on one side of the trough idler frame, a connecting rod being horizontally arranged on the bearing member near the side of the trough idler frame, the connecting rod being able to pass through the bracket of the trough idler frame from one side and be threadedly connected to the fastening plate, the fastening plate being able to abut against the bracket of the trough idler frame on the other side; a lifting assembly, the lifting assembly being arranged on the bearing member, the upper part of the lifting assembly being provided with the support member, the support member being able to lift the belt.
[0007] This utility model allows the tooling to be directly installed on the crossbeam of the trough-type idler roller frame through the fastening plate and the limiting plate, which shortens the distance between the support and the belt, reduces the requirements for the stroke range of the lifting component, and can meet the needs of a variety of belt conveyor models. In addition, the short stroke of the lifting component makes it easy to achieve lightweight tooling, which in turn makes it easy to carry and transport.
[0008] Furthermore, the limiting plate is an arc-shaped plate with its opening facing the fastening plate, and the limiting plate can be tightly attached to the crossbeam of the trough-shaped idler frame.
[0009] This invention increases the contact area with the crossbeam of the slotted roller frame by using an arc-shaped plate, resulting in a more stable connection.
[0010] Furthermore, the limiting plate is connected to the lower surface of the carrier through a support rod, which is inclined.
[0011] This utility model connects the limiting plate and the load-bearing component by setting a support rod, which enables the load-bearing component, the limiting plate and the fastening plate to form a triangular structure, enhancing stability and making the load-bearing component less prone to deformation after being subjected to force, thus ensuring the reliability of the support.
[0012] Furthermore, the support member has a U-shaped structure with the opening facing downwards. The support member includes a base plate, and two reinforcing plates are arranged vertically at the lower part of the base plate. The connecting rod is arranged horizontally on the outer surface of the reinforcing plate near the trough-shaped roller frame, and the end of the support rod is connected to the base plate.
[0013] This invention enhances the strength of the support component and prevents deformation by incorporating a U-shaped support member.
[0014] Furthermore, the lifting assembly includes an electric scissor jack and a support base. The support base has an upward-opening U-shaped structure and is located on top of the electric scissor jack. The support member is located inside the support base.
[0015] Furthermore, the support member includes a crossbar disposed within the support base. The crossbar supports the bottom of the belt, and a limiting rod is obliquely disposed on the crossbar, which supports the side of the belt.
[0016] This invention, by setting a limiting rod, can achieve full-range support of the belt on the upper part of the idler roller that needs to be replaced, thereby increasing the support range and preventing deformation of the support components after long-term use.
[0017] Furthermore, a reinforcing rod is vertically provided between the limiting plate and the crossbar.
[0018] Furthermore, the crossbar is capable of moving within the support base along its own length.
[0019] This invention, by setting the crossbar to be adjustable along its own length, can adjust the support position according to the width of the belt, ensuring that the limiting plate can always support the belt and avoiding the situation where the crossbar is supported alone.
[0020] As can be seen from the above technical solutions, this utility model has the following advantages: This utility model provides a tooling for replacing idler rollers of a belt conveyor. Through the action of a fastening plate and a limiting plate, this tooling can be directly installed on the crossbeam of the idler roller frame, shortening the distance between the support and the belt. It also reduces the requirements for the stroke range of the lifting assembly, making it suitable for a wide range of belt conveyor models. Furthermore, the short stroke of the lifting assembly facilitates lightweight tooling, making it easier to carry and transport. The use of an arc-shaped plate increases the contact area with the crossbeam of the idler roller frame, resulting in a more stable connection. The connection between the limiting plate and the load-bearing component is achieved through the use of a support rod. The triangular structure formed by the load-bearing component, limiting plate, and fastening plate enhances stability and prevents deformation of the load-bearing component under stress, ensuring reliable support. The U-shaped load-bearing component strengthens its structure and prevents deformation. The limiting rod provides full support for the belt above the idler roller that needs replacement, increasing the support range and preventing deformation of the support component over long-term use. The adjustable crossbar, designed to follow its length, allows for adjustment of the support position according to the belt width, ensuring the limiting plate always supports the belt and preventing the crossbar from supporting the belt alone.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0028] like Figure 1 and Figure 2As shown in the figure, this specific embodiment provides a tooling for replacing belt conveyor idlers, including a support member 3, a mounting base 1, and a lifting assembly 2; the mounting base 1 includes a bearing member 101, a limiting plate 104, and a fastening plate 105. The limiting plate 104 is connected to the bearing member 101 and can abut against the trough idler frame crossbeam 4. The bearing member 101 is located on the upper side of the trough idler frame crossbeam 4. A connecting rod 103 is horizontally arranged on the bearing member 101 near the trough idler frame, and the connecting rod 103 can pass through from one side. The bracket 5 of the trough-type idler frame is threadedly connected to the fastening plate 105. The connecting rod 103 is provided with a threaded hole, and the fastening plate 105 is provided with a matching bolt. After tightening the fastening plate 105, the fastening plate 105 can abut against the bracket 5 of the trough-type idler frame on the other side. Through the action of the fastening plate 105 and the limiting plate 104, the mounting base 1 is mounted and supported on the crossbeam 4 of the trough-type idler frame. The lifting assembly 2 is provided on the bearing member 101. The upper part of the lifting assembly 2 is provided with the support member 3, which can lift the belt.
[0029] This specific embodiment allows the tooling to be directly installed on the crossbeam 4 of the trough-type idler frame through the fastening plate 105 and the limiting plate 104. This shortens the distance between the support 3 and the belt, reduces the stroke range requirement of the lifting component 2, and can meet the needs of many types of belt conveyors. Furthermore, the small stroke of the lifting component 2 facilitates the lightweighting of the tooling, making it easier to carry and transport.
[0030] The limiting plate 104 can be a flat plate, since the crossbeam 4 is a cylindrical structure, such as Figure 1 , Figure 3 and Figure 4 As shown in this specific embodiment, in order to increase the contact area between the limiting plate 104 and the crossbeam 4, the limiting plate 104 is an arc-shaped plate, and the diameter of the limiting plate 104 is customized according to the diameter of the crossbeam 4. The opening of the limiting plate 104 faces the fastening plate 105, and the limiting plate 104 can be tightly attached to the crossbeam 4 of the trough roller frame. Furthermore, the central angle of the limiting plate 104 is 180°, and two limiting plates 104 are provided along the length direction of the crossbeam 4 of the trough roller frame.
[0031] The limiting plate 104 can be welded to the bearing member 101, such as... Figure 1 and Figure 3As shown, in this specific embodiment, the limiting plate 104 is connected to the lower surface of the bearing member 101 via a support rod 102, which is inclined downwards. With this configuration, since the bearing member 101 is located on one side of the upper part of the crossbeam 4, and the support rod 102 is inclined, the support rod 102 transmits the force of the belt to the limiting plate 104 at an incline, causing the limiting plate 104 to tend to rotate downwards relative to the crossbeam 4. However, because the fastening plate 105 abuts against the bracket 5 on the upper part of the crossbeam 4, the limiting plate 104 is blocked by the bracket 5, preventing it from rotating. This ensures the reliability of the connection between the mounting base 1 and the crossbeam 4, thereby ensuring the reliability of the support. Furthermore, the force points on the bearing member 101, the limiting plate 104, and the fastening plate 105 form a triangle, resulting in a triangular force distribution on the mounting base 1, which provides higher stability, prevents deformation, and extends service life.
[0032] Since the load-bearing component 101 bears the weight of the belt, in order to enhance the strength of the load-bearing component 101, such as Figure 1 and Figure 3 As shown in this specific embodiment, the bearing member 101 has a U-shaped structure with the opening facing downwards. The bearing member 101 includes a base plate 1011, and two reinforcing plates 1012 are arranged vertically at the lower part of the base plate 1011. The connecting rod 103 is arranged horizontally on the outer surface of the reinforcing plate 1012 near the trough-shaped roller frame. The end of the support rod 102 is welded to the base plate 1011. Furthermore, the bearing member 101 is made of channel steel. One end of the support rod 102 is welded to an inner corner of the channel steel away from the trough-shaped roller frame, and the other end is welded to the limiting plate 104.
[0033] like Figures 1 to 3As shown, in this specific embodiment, the lifting assembly 2 includes an electric scissor jack 201 and a support base 202. The support base 202 has an upward-opening U-shaped structure and is located on top of the electric scissor jack 201. The support member 3 is located inside the support base 202. To facilitate storage and transportation of this tooling, the lifting assembly 2 can be separated from the carrier 101, and the support member 3 can be separated from the support base 202. In this specific embodiment, during use, the lifting assembly 2 can be directly placed on the upper surface of the carrier 101, and pressed onto the carrier 101 by the force of the belt. The support member 3 includes a crossbar 301, which is located inside the support base 202. The width of the crossbar 301 is smaller than the opening width of the support base 202, and the crossbar 301 can support... At the bottom of the belt, a limiting rod 302 is inclinedly provided on the crossbar 301. The limiting rod 302 and the crossbar 301 form a support angle. The limiting rod 302 can support the side of the belt. In use, the crossbar 301 of the support member 3 is placed in the support seat 202. Furthermore, when the width of the crossbar 301 is less than the opening width of the support seat 202, the crossbar 301 can move along its own length direction within the support seat 202. With this setting, the position of the support member 3 can be adjusted according to the width of the belt, ensuring that the part of the belt opposite to the idler roller that needs to be replaced is supported at the support angle formed by the crossbar 301 and the limiting rod 302, avoiding the crossbar 301 from being subjected to force alone and deforming and breaking after a long time. Furthermore, a reinforcing rod 303 is also vertically provided between the limiting plate 104 and the crossbar 301.
[0034] The working process of this fixture is as follows: like Figure 4 As shown, place the limiting plate 104 at the corresponding position on the crossbeam 4, ensuring that the support 3 is opposite to the part of the belt that needs to be lifted, while the connecting rod 103 passes through the bracket 5 on the crossbeam 4; install the fastening plate 105 until the fastening plate 105 abuts against the bracket 5, and the mounting seat 1 is firmly installed on the crossbeam 4; place the lifting assembly 2 on the bearing 101; place the crossbar 301 of the support frame on the support seat 202 and adjust its position so that the part of the belt being lifted can contact both the limiting rod 302 and the crossbar 301; control the lifting assembly to lift, and the belt is lifted by the support frame to the set height, with sufficient distance between the belt and the idler roller that needs to be replaced, facilitating the replacement of the idler roller; after the replacement is completed, control the lifting assembly 2 to descend, the belt is lowered back to its original position, remove the lifting assembly 2 and the support 3, and separate the mounting seat 1 from the crossbeam 4.
[0035] As can be seen from the above specific embodiments, this utility model has the following beneficial effects: 1. Through the action of fastening plate 105 and limiting plate 104, this tooling can be directly installed on the crossbeam 4 of the trough-type idler roller frame, which shortens the distance between the support 3 and the belt, reduces the stroke range requirement of the lifting component 2, and can meet the needs of many types of belt conveyors. In addition, the small stroke of the lifting component 2 makes it easy to achieve lightweight tooling, which makes it easy to carry and transport. 2. By using an arc-shaped plate to increase the contact area with the crossbeam 4 of the trough-type roller frame, the connection is more stable; by setting a support rod 102 to connect the limiting plate 104 and the bearing member 101, the bearing member 101, the limiting plate 104 and the fastening plate 105 can form a triangular structure, which enhances stability and makes it less prone to deformation after the bearing member 101 is subjected to force, thus ensuring the reliability of the support. 3. By setting the U-shaped support member 101, the strength of the support member 101 can be enhanced and deformation can be prevented; 4. By setting the limit rod 302, the belt on the upper part of the idler roller that needs to be replaced can be lifted throughout the entire process, increasing the support range and preventing the support component 3 from deforming after long-term use; 5. By setting the crossbar 301 to be adjustable along its own length, the support position can be adjusted according to the width of the belt, ensuring that the limiting plate 104 can always support the belt and avoiding the situation where the crossbar 301 is supported alone.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
