Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, and particularly relates to a movable support for replacing a roller of a belt conveyor. Background Art

[0002] Belt conveyors have the advantages of strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can be conveniently programmed and automated. They are widely used in the field of ore transportation.

[0003] The current belt conveyor includes rollers arranged at both ends and a belt sleeved on the two rollers. The belt is driven to rotate by the friction force between the rollers and the belt when the rollers rotate. In ore transportation, the belt and the rollers often bear large forces, so that the rollers are easily damaged during the long-term friction with the belt. Therefore, the damaged rollers need to be replaced.

[0004] At present, the belt conveyors for transporting ore are all large in size, and the internal rollers are often very heavy, weighing up to several tons. When replacing the rollers, external manual hoisting machinery such as a manual chain hoist needs to be used to lift them manually, and while lifting the rollers, the rollers are moved along the direction of the central axis of the rollers so that the rollers are disengaged from the inside of the belt.

[0005] However, for relatively heavy rollers, it is easy to lift them, but it is difficult to slowly translate the rollers manually while lifting them to disengage them from the inside of the belt. Moreover, during the translation of the rollers, the rollers are prone to shaking and are likely to collide with other components, causing damage to the equipment and also causing injuries to personnel. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a movable support for replacing a roller of a belt conveyor to solve the technical problem that it is not easy to disengage and place the roller from the inside of the belt in the prior art when replacing the internal roller of the conveyor belt.

[0012] A first pin hole is provided on the connecting rod, and a second pin hole is provided on the side of the support plate. When the movable support column is in the initial position before rotating and folding, the first pin hole and the second pin hole coincide, so that a pin can be inserted to fix the movable support column.

[0013] As a preferred embodiment of the present utility model, the shortest distance between the installation position of the movable support column on the support plate and the end of the support plate is greater than the width of the movable support column.

[0014] As a preferred embodiment of the present utility model, a plurality of mounting brackets are fixedly installed on the inner wall of the support plate. The movable roller includes a rotating roller. Connecting shafts are provided at both ends of the rotating roller.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] As Figure 1 And Figure 2 shown, the present invention provides a movable bracket for replacing the drum of a belt conveyor, mainly by providing a support plate 1 and a movable roller 2 to assist in replacing the drum.

[0029] The movable bracket for replacing the drum of a belt conveyor includes two support plates 1 and a plurality of movable rollers 2 arranged between the two support plates 1. The movable rollers 2 rotate when subjected to an external force, and the plurality of movable rollers 2 are arranged in parallel to form a free rolling platform in the length direction of the support plate 1;

[0030] A fixed support column 101 is provided at one end of the support plate 1, and a movable support column 102 is provided at the other end. One end of the movable support column 102 is connected to the support plate 1 through a rotating shaft, and can rotate around the rotating shaft to one end of the fixed support column 101, and can be fixed.

[0031] The shortest distance between the installation position of the movable support column 102 on the support plate 1 and the end of the support plate 1 is greater than the width of the movable support column 102 .

[0032] Currently, when replacing some heavier rollers, it is necessary to first lift the roller and then push it to make it detach from the belt. However, due to the large weight and volume of the roller, the operation is difficult, and the roller will shake during the pushing process, which is dangerous. Therefore, it is necessary to develop a device that can easily replace the roller.

[0033] In this embodiment, a plurality of rolling movable rollers 2 are provided to form a free rolling platform in the length direction of the support plate 1, and a rotating and retractable movable support column 102 is provided, so that the support plate 1 drives the movable rollers 2 to enter the belt of the belt conveyor. When removing the roller, the removed roller is hoisted and placed at one end of the bracket, and then the roller is pushed to the other end of the bracket, so that the roller can be removed from the belt without applying external force to move the roller when hoisting the roller; when installing the roller, the opposite process of disassembly is followed, making replacement of the roller more labor-saving and safe.

[0034] When disassembling the roller, 1. In the initial state, the movable support column 102 is vertically arranged with the support plate 1, and the connecting rod 105 is fixed with the support plate 1 by the pin 106. At this time, the support plate 1 is moved to the side of the conveyor;

[0035] 2. Lift the roller to be replaced so that one end of the support plate 1 is overlapped on the conveyor so that the conveyor supports the support plate 1, and then remove the pin 106 of the fixed connecting rod 105 to release the limit of the movable support column 102;

[0036] 3. Rotate the movable support column 102 toward the fixed support column 101 until the movable support column 102 is parallel to the support plate 1. At this time, the entire support plate 1 moves toward the inside of the conveyor, and the movable roller 2 is just at the bottom of the lifted drum;

[0037] 4. Slowly move the lifted roller down until the weight of the roller is all on the movable roller 2. At this time, the roller is placed at one end of the free rolling platform. At this time, by pushing the roller, the roller moves on the free rolling platform, and the roller moves to the other end of the free rolling platform, and then the roller is transferred out of the belt. Because the movable roller 2 rolls, it is more labor-saving to push the roller.

[0038] When installing the roller, the installation steps are opposite to the above steps. Move the roller to be installed inside the belt through the support plate 1, then lift the roller to be installed, and move the device out.

[0039] Specifically, a sliding rod 103 is arranged on the support plate 1. Both ends of the sliding rod 103 are arranged on the support plate 1 through fixing blocks, and a sliding block 104 is arranged on the sliding rod 103;

[0040] The movable support column 102 is connected to the sliding block 104 through a connecting rod 105. Both ends of the connecting rod 105 are rotatably connected, and the movable support column 102 and the sliding block 104 act synchronously through the connecting rod 105;

[0041] A first pin hole is arranged on the connecting rod 105, and a second pin hole is arranged on the side of the support plate 1. When the movable support column 102 is in the initial position before rotating and folding, the first pin hole and the second pin hole coincide, so as to insert a pin 106 to fix the movable support column 102.

[0042] The movable support column 102 is fixed through the connecting rod 105, so as to support the support plate 1.

[0043] In order to better retract the movable support column 102, a third pin hole is opened on the movable support column 102. When the movable support column 102 rotates under the action of an external force towards one end of the fixed support column 101 and is parallel to the support plate 1, the movable support column 102 is retracted. At this time, the third pin hole coincides with the second pin hole, and the movable support column 102 is fixed by inserting a pin 106.

[0044] As Figure 3 and Figure 4 shown, the specific connection method between the movable roller 2 and the support plate 1 is that a plurality of mounting brackets 107 are fixedly installed on the inner wall of the support plate 1. The movable roller 2 includes a rotating roller 201. Connecting shafts 202 are arranged at both ends of the rotating roller 201. The rotating roller 201 is rotatably connected to the connecting shafts 202, and the connecting shafts 202 are movably clamped in the mounting brackets 107 to support the rotating roller 201. The support plate 1 and the movable roller 2 are fixed by the clamping method of the mounting brackets 107 and the connecting shafts 202. When the movable roller 2 is worn due to long-term use of the device, it is also more convenient to replace the movable roller 2.

[0045] Preferably, the cross-section of the rotating roller 201 is circular, and the diameter of the middle cross-section of the rotating roller 201 is smaller than that of the cross-sections at both ends thereof, so that the height of the top of the middle part of the rotating roller 201 is lower than the height of the tops of both ends thereof. When the movable roller 2 supports the roller, the placing direction of the roller is perpendicular to the placing direction of the movable roller 2. The special structure of the rotating roller 201 can not only support the roller, but also keep the roller at the middle position of the rotating roller 201 during the transfer process, improving the stability of the transfer.

[0046] In order to facilitate the movement of the device, walking wheels 108 are installed at the bottoms of the fixed support column 101 and the movable support column 102.

[0047] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
