Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a telescopic body buffer device for a tunneling roadway belt conveyor. Background Technology

[0002] In coal mine tunneling and roadway operations, belt conveyors serve as the "throat" of material transportation. Their telescopic bodies need to be adjusted to continuously adapt to the advancing face. The impact at the material receiving point and the vibration during operation remain the core pain points restricting equipment reliability. Currently, the mainstream buffering solutions in the industry mainly consist of buffer rollers and simple buffer beds.

[0003] Existing belt conveyor telescopic body buffer devices suffer from the strong impact of the gravitational potential energy and kinetic energy of falling materials on the idler rollers, and the energy absorption effect of the external rubber rings on the idler rollers is limited. The bearings of the buffer idler rollers are prone to failure after long-term impact, causing the rollers to jam, which not only aggravates belt wear and requires frequent replacement, but also results in high maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a telescopic body buffer device for a tunneling roadway belt conveyor.

[0005] This utility model is achieved by the following technical solution: a telescopic body buffer device for a tunneling roadway belt conveyor, including a support rod, a mounting plate fixedly connected to the top of the support rod, a buffer pad fixedly connected to the top of the mounting plate, a mounting frame fixedly connected to the front and rear ends of the support rod, a sliding mechanism provided on both sides of the support rod, and a buffer mechanism provided at the bottom of the mounting frame.

[0006] The above technical solution involves setting three support rods, with mounting plates located at the front and rear ends of the support rods.

[0007] As a further improvement to the above solution, the sliding mechanism includes a lifting rod, a sliding groove is provided on one side of the lifting rod, a guide rod is fixedly connected to the bottom of the inner wall of the sliding groove, a first spring is fixedly connected to the bottom of the inner wall of the sliding groove, a sliding block is slidably connected to the surface of the guide rod, a roller rod is fixedly connected to one side of the sliding block, and a roller is rotatably connected to the surface of the roller rod.

[0008] The above technical solution allows for the installation of four lifting masts, with two lifting plates installed on each side of the two mounting plates.

[0009] As a further improvement to the above solution, the lifting rod is located at one end of the mounting frame, and one end of the lifting rod is fixedly connected to one end of the mounting frame.

[0010] As a further improvement to the above solution, the inner wall of the sliding groove is slidably connected to the surface of the sliding block, and the surface of the guide rod is located inside the first spring.

[0011] Through the above technical solution, the guide rod is the "limiting guide" part of the sliding block. It is vertically fixed to the bottom of the inner wall of the sliding groove, passes through the sliding block and the first spring, and restricts the sliding block to slide up and down along the guide rod. This prevents the sliding block from deviating and causing buffer failure, while also preventing the first spring from bending laterally when it extends and retracts, thus ensuring the stability of the lateral buffer.

[0012] As a further improvement to the above solution, one end of the first spring is fixedly connected to the bottom of the sliding block.

[0013] With the above technical solution, one side of the sliding block is fixed to the roller rod to receive the lateral force of the belt transmitted by the roller; it can slide along the guide rod to convert the lateral force into compression of the first spring, realizing the transmission and buffering of force, and avoiding the force from acting directly on the lifting rod or the mounting frame.

[0014] As a further improvement to the above solution, the buffer mechanism includes a bolt, the surface of which is penetrated by a connecting plate, and a second spring is fixedly connected to the top of the connecting plate.

[0015] Through the above technical solution, the "core execution" component of the second spring longitudinal primary buffer is fixed to the connecting plate at the top and can be adapted to the machine frame at the bottom according to the installation requirements. When the device is subjected to longitudinal vibration and material impact, it absorbs energy through its own elastic deformation, alleviates the direct effect of longitudinal impact on the support rod and mounting plate, and balances the overall force of the device.

[0016] As a further improvement to the above solution, the bolt is located at the bottom of the mounting plate, and the surface of the bolt is connected to the internal thread of the mounting plate.

[0017] Through the above technical solution, the "fastening connection" part of the bolt buffer mechanism has a surface that penetrates the connecting plate and is threaded to the inside of the mounting plate, which firmly fixes the connecting plate and the second spring to the bottom of the mounting plate, preventing the buffer mechanism from loosening and falling off due to vibration, and at the same time facilitating later disassembly and maintenance, and adjusting the initial installation state of the second spring.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention incorporates a first spring. When the belt drives the drum to rotate, if there is material impact or tension change, the sliding block will buffer the force by sliding along the guide rod and compressing the first spring. This avoids the drum and drum rod directly bearing rigid impact, reduces problems such as drum bearing wear and drum rod deformation, extends the service life of the drum assembly, and reduces component maintenance and replacement costs.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example: Please combine Figure 1-5 The telescopic body buffer device of the tunneling roadway belt conveyor in this embodiment includes a support rod 1, a mounting plate 2 fixedly connected to the top of the support rod 1, a buffer pad 3 fixedly connected to the top of the mounting plate 2, a mounting frame 4 fixedly connected to the front and rear ends of the support rod 1, a sliding mechanism 5 provided on both sides of the support rod 1, and a buffer mechanism 6 provided at the bottom of the mounting frame 4.

[0023] The sliding mechanism 5 includes a lifting rod 51. A sliding groove 52 is provided on one side of the lifting rod 51. A guide rod 53 is fixedly connected to the bottom of the inner wall of the sliding groove 52. A first spring 54 is fixedly connected to the bottom of the inner wall of the sliding groove 52. A sliding block 55 is slidably connected to the surface of the guide rod 53. A roller rod 56 is fixedly connected to one side of the sliding block 55. A roller 57 is rotatably connected to the surface of the roller rod 56. The mounting bracket 4 is fixed to the front and rear ends of the support rod 1. The four lifting rods 51 connected to one end of the bracket (two are installed on each side of the two mounting plates 2) become the carrier of the sliding mechanism 5. In the sliding groove 52 on one side of the lifting rod 51, the guide rod 53 slides... Block 55 serves as a limiting and guiding element. When the belt conveyor generates a lateral force or the belt tension changes, the sliding block 55 will slide up and down along the guide rod 53. At this time, the first spring 54 (the guide rod 53 passes through the inside of the first spring 54 to ensure the spring's extension and contraction stability) which is fixedly connected to the bottom of the inner wall of the sliding groove 52 and the bottom of the sliding block 55 will extend and contract accordingly. The elastic potential energy of the spring is converted to offset the force, and the roller 57 and roller 57 rod 56 are prevented from directly bearing rigid impact. This reduces problems such as roller 57 bearing wear and roller 57 rod 56 deformation, extends the service life of the roller 57 assembly, and reduces the cost of component maintenance and replacement.

[0024] The lifting rod 51 is located at one end of the mounting frame 4, and one end of the lifting rod 51 is fixedly connected to one end of the mounting frame 4.

[0025] The inner wall of the sliding groove 52 is slidably connected to the surface of the sliding block 55, and the surface of the guide rod 53 is located inside the first spring 54.

[0026] One end of the first spring 54 is fixedly connected to the bottom of the sliding block 55.

[0027] The buffer mechanism 6 includes a bolt 61, through which a connecting plate 62 passes. A second spring 63 is fixedly connected to the top of the connecting plate 62. The device is based on a support structure of three support rods 1. The mounting plates 2 fixed to the front and rear ends of the support rods 1 are not only connected to the top of the buffer pad 3 to initially alleviate the direct impact when the belt conveys materials, but are also fixed to the connecting plate 62 at the bottom by bolts 61. The bolts 61 and the mounting plate 2 are connected by threads to ensure a stable connection. The second spring 63 at the top of the connecting plate 62 can undergo elastic deformation when the device is subjected to force, further absorbing the longitudinal vibration and impact from the belt conveyor during operation, thus playing a primary buffering role.

[0028] Bolt 61 is located at the bottom of mounting plate 2, and the surface of bolt 61 is connected to the internal thread of mounting plate 2.

[0029] The implementation principle of the telescopic body buffer device for a tunneling roadway belt conveyor in this embodiment is as follows: The device is based on three support rods 1 as the basic support structure. The mounting plate 2 fixed at the front and rear ends of the support rods 1 is not only connected to the top of the buffer pad 3 to initially alleviate the direct impact when the belt conveys materials, but also fixed to the bottom of the connecting plate 62 by bolts 61. The bolts 61 and the mounting plate 2 are connected by threads to ensure a stable connection. The second spring 63 at the top of the connecting plate 62 can undergo elastic deformation when the device is subjected to force, further absorbing the longitudinal vibration and impact from the belt conveyor during operation, thus playing a primary buffering role. Meanwhile, the mounting bracket 4 is fixed to the front and rear ends of the support rod 1. The four lifting rods 51 connected to one end (two are installed on each side of the two mounting plates 2) become the carrier of the sliding mechanism 5. In the sliding groove 52 on one side of the lifting rod 51, the guide rod 53 plays a limiting and guiding role for the sliding block 55. When the belt conveyor generates a lateral force or the belt tension changes, the sliding block 55 will slide up and down along the guide rod 53. At this time, the first spring 54 (the guide rod 53 passes through the inside of the first spring 54 to ensure the spring extension and contraction stability) which is fixedly connected to the bottom of the inner wall of the sliding groove 52 and the bottom of the sliding block 55 will extend and contract accordingly. The elastic potential energy of the spring is converted to offset the force, and the roller 57 and the roller 57 rod 56 are prevented from directly bearing rigid impact, reducing the wear of the roller 57 bearing and the deformation of the roller 57 rod 56, extending the service life of the roller 57 assembly and reducing the cost of component maintenance and replacement.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
