Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyor equipment, in particular to a novel push beam assembly. Background Technique

[0002] The ultra-heavy scraper conveyor is an important conveying equipment in the coal mining face underground in coal mines. It is usually used in conjunction with the shearer support and is suitable for the long-arm mining face of gently inclined medium-thick coal seams with an inclination of less than 15°. Its main purpose is to transport the coal mined in the working face to the head, and then unload it onto the belt conveyor, and transport it to the ground through equipment such as the belt conveyor. Therefore, the normal operation of the ultra-heavy scraper conveyor directly affects the production capacity of the working face. When coal mining is carried out in the working face, the ultra-heavy scraper conveyor needs to cooperate with the shearer for operation, which requires continuous pushing and pulling of the scraper conveyor. The push beam assembly plays a key role in the pushing and pulling process of the scraper conveyor. At present, the pushing component is arranged on the side of the head and tail assemblies, and a connecting part needs to be added to connect the pushing component. In order to connect the pushing part, the height of the head and tail needs to be increased. However, when the shearer is installed on the conveyor, the change in the height of the head and tail will cause the height of the shearer to increase accordingly, and then the coal mine at the lower end cannot be effectively mined, resulting in a reduction in the mining volume. Content of the Utility Model

[0003] The purpose of the utility model is to provide a novel push beam assembly to solve the problems that in the prior art, a connecting part needs to be added to connect the pushing component, and at the same time, in order to connect the pushing part, the height of the head and tail needs to be increased, resulting in the increase of the height of the shearer, and then the coal mine at the lower end cannot be effectively mined, resulting in a reduction in the mining volume. At the same time, when limiting the position of the push seat, the positioning part needs to be frequently pulled out and connected. When the operator fails to limit the position of the push seat due to negligence, the workpiece will be damaged, affecting the work efficiency.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A novel push beam assembly includes a tail, a push frame body, a connecting block, a push cross beam, a push seat, and an auxiliary positioning device arranged on the push seat. A plurality of installation grooves are evenly opened on the left and right sides of the tail, and the installation grooves are symmetrically arranged in pairs and are respectively located at the front and rear ends of the tail. A push frame body is arranged at the opening end of the installation groove, and a connecting block is connected between the push frame body and the tail. One end of the connecting block is slidably matched with the installation groove, and the other end of the connecting block is connected with the push frame body. The end of the push frame body far from the tail is connected with a push cross beam. A chute is opened on the push cross beam, and a plurality of pin holes are evenly opened on the chute. The pin holes are symmetrically arranged in pairs. A push seat is connected to the chute, and the push seat is slidably matched with the push cross beam. An installation hole corresponding to the pin hole is opened on the push seat.

[0005] The auxiliary positioning device includes a first connecting rod, a second connecting rod, a positioning plate, and a return spring. The positioning plate is arranged at the top of the mounting hole formed in the pushing seat. A threaded hole corresponding to the mounting hole is formed in the positioning plate. The left and right sides of the positioning plate are symmetrically and respectively hinged with the second connecting rods. The other ends of the second connecting rods are respectively hinged with the first connecting rods. The other ends of the first connecting rods are respectively hinged to the left and right sides of the pushing seat. A connecting hole is further formed in the pushing seat and is respectively arranged at the left and right sides of the mounting hole. A return spring is arranged in the connecting hole. One end of the return spring abuts against the inner wall of the connecting hole, and the other end abuts against the bottom end of the positioning plate.

[0006] Preferably, a positioning hole is formed at the connection between the connecting block and the tail of the machine. The positioning hole corresponds to a preset linkage hole on the tail of the machine. A positioning bolt is arranged in the positioning hole. The positioning bolt penetrates through the tail of the machine, the connecting block and is fastened by a nut.

[0007] Preferably, a positioning pin is arranged in the threaded hole on the positioning plate. The contact end of the positioning pin with the positioning plate is provided with threads. The positioning pin is screwed into the positioning plate and penetrates through the positioning plate and the bottom end of the pushing seat and is inserted into the pin shaft hole.

[0008] Preferably, a reinforcing rib is connected between the connecting block and the pushing cross beam and is connected to the pushing frame body to connect the connecting block, the pushing cross beam and the pushing frame body into a whole for increasing stability.

[0009] Preferably, a hand pull rod is further arranged on the positioning plate for lifting the auxiliary positioning device.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] By forming a mounting groove on the tail of the machine, the connecting block can be directly inserted into the connecting groove and fastened to the tail of the machine with a positioning bolt. Such a design avoids adding additional connecting components, thereby avoiding the problem of increasing the height of the head and the tail of the machine, ensuring that the coal shearer can effectively collect the coal at the bottom. At the same time, the slot type connection is adopted, making the device structure more compact and facilitating installation underground.

[0012] In addition, an auxiliary positioning device is further arranged on the pushing seat of the device. When the pushing seat slides on the pushing cross beam, the operator can pull out the positioning pin by pulling the hand pull rod, thereby unlocking the pushing seat for sliding. When the pushing seat slides to the predetermined position, the hand pull rod is released, and the return spring will automatically drive the positioning plate to reset and insert the positioning pin back into the pin shaft hole on the pushing cross beam, thereby realizing limit fixation. This design not only simplifies the installation process but also improves the operation convenience and positioning accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-3, an embodiment provided by the present utility model: a novel push beam assembly, including a machine tail 1. The machine tail 1 serves as the main support structure of the system, providing an overall framework and an installation foundation, a push frame body 2, a connecting block 3, a push cross beam 5, a push seat 7, and an auxiliary positioning device 8 provided on the push seat 7. A number of installation slots are evenly opened on both the left and right sides of the machine tail 1. The installation slots are symmetrically arranged in pairs and are respectively located at the front and rear ends of the machine tail 1. A push frame body 2 is provided at the open end of the installation slot. The push frame body 2 supports and fixes the push cross beam 5 and is connected to the machine tail 1 to form a stable structural support. A connecting block 3 is connected between the push frame body 2 and the machine tail 1. One end of the connecting block 3 is slidably fitted in the installation slot. The connecting block 3 connects the push frame body 2 and the machine tail 1. The card slot connection design simplifies the installation process, especially during underground operations, making the installation more convenient and enabling the push frame body 2 and the machine tail 1 to form an integral whole. This design avoids adding additional connection components to the machine tail 1, thereby preventing an increase in the overall height of the machine tail 1. This can keep the height of the shearer unchanged and avoid reducing the coal mining volume. This design makes the installation underground faster and more convenient. At the same time, since the machine tail 1 and the push frame body 2 are spliced into an integral whole, the overall height is reduced, thereby increasing the undercut amount of the shearer and increasing the coal mining volume. During the installation process, the connecting block 3 is inserted into the installation slot and positioned by a positioning bolt to ensure the accuracy of the position. At the same time, the connection component is designed in a sliding fit form, reducing additional connection components and making the overall structure more compact. The other end of the connecting block 3 is connected to the push frame body 2. The end of the push frame body 2 away from the machine tail 1 is connected to a push cross beam 5. The push cross beam 5 provides a guide rail for the push seat 7 to slide, allowing the push seat 7 to move on the cross beam. A chute 6 is opened on the push cross beam 5. A number of pin holes are evenly opened on the chute 6. The pin holes are symmetrically arranged in pairs. The push seat 7 is connected to the chute 6 and is slidably fitted to the push cross beam 5. An installation hole corresponding to the pin hole is opened on the push seat 7. The function of the push seat 7 is to connect the push part and the external hydraulic support. A positioning hole is opened at the connection between the connecting block 3 and the machine tail 1. The positioning hole corresponds to a preset linkage hole on the machine tail 1. A positioning bolt is arranged in the positioning hole. The positioning bolt penetrates through the machine tail 1 and the connecting block 3 and is tightened by a nut. A reinforcing rib 4 is connected between the connecting block 3 and the push cross beam 5 and is connected to the push frame body 2 to connect the connecting block 3, the push cross beam 5, and the push frame body 2 into an integral whole for increasing stability. The reinforcing rib 4 enhances the stability between the connecting block 3 and the push cross beam 5, making the connection of the connecting block 3, the push cross beam 5, and the push frame body 2 into an integral whole reduce the deformation or loosening of the structure and reduce the displacement or vibration caused by operation.

[0023] Install the connecting block 3 on the pushing frame body 2. At the same time, connect the pushing cross beam 5 to the pushing frame body 2. Then connect the reinforcing rib 4 between the connecting block 3 and the pushing cross beam 5. Then insert the connecting block 3 into the installation groove opened in the tail 1 of the machine. At the same time, insert the positioning bolt into the linkage hole opened in the tail 1 of the machine and the positioning hole on the connecting block 3 for limit fixation. Then install the pushing seat 7 into the sliding groove 6 opened on the pushing cross beam 5, and the installation can be completed.

[0024] Embodiment 2: Please refer to Figure 4 , on the basis of Embodiment 1, it also has the following structure:

[0025] The auxiliary positioning device 8 includes a first connecting rod 801, a second connecting rod 802, a positioning plate 803, and a return spring 806. The positioning plate 803 is arranged at the top end of the installation hole opened in the pushing seat 7. Threaded holes corresponding to the installation hole are opened on the positioning plate 803. The left and right sides of the positioning plate 803 are symmetrically and respectively hinged with the second connecting rod 802. The other ends of the second connecting rods 802 are respectively hinged with the first connecting rod 801. The other ends of the first connecting rods 801 are respectively hinged to the left and right sides of the pushing seat 7. Connecting holes are also opened on the pushing seat 7. The first connecting rod 801 and the second connecting rod 802 connect the positioning plate 803 and the pushing seat 7, and at the same time provide additional support and positioning to prevent the positioning plate 803 from shifting, so that the positioning plate 803 can be accurately adjusted and positioned on the pushing seat 7. The connecting holes are respectively arranged at the left and right sides of the installation hole. A return spring 806 is arranged in the connecting hole. One end of the return spring 806 abuts against the inner wall of the connecting hole, and the other end abuts against the bottom end of the positioning plate 803. The return spring 806 provides elastic force by connecting with the inner wall of the connecting hole and the positioning plate 803, so that the positioning plate 803 can automatically return to its original position after adjustment. Insert the positioning pin 805 into the pin shaft hole to ensure the reliability of positioning.

[0026] A positioning pin 805 is arranged in the threaded hole on the positioning plate 803. The contact end of the positioning pin 805 with the positioning plate 803 is provided with threads. The positioning pin 805 is screwed into the positioning plate 803 and penetrates through the positioning plate 803 and the bottom end of the pushing seat 7 and is inserted into the pin shaft hole. The positioning plate 803 connects the positioning pin 805 through the opened threaded hole. The contact end of the positioning pin 805 with the positioning plate 803 is provided with threads, so that when the positioning plate 803 moves, the positioning pin 805 will not fall off, and there is no need for frequent installation and disassembly. At the same time, when replacing the positioning pin 805, the positioning pin 805 can be screwed out for replacement.

[0027] The positioning plate 803 is further provided with a hand pull rod 804 for lifting the auxiliary positioning device 8, so that the operator can conveniently adjust or release the auxiliary positioning device 8. During use, first pull the hand pull rod 804. At the same time, the second connecting rod 802 rotates, driving the first connecting rod 801 to rotate. At the same time, the positioning plate 803 rises, lifting the return spring 806 and the positioning pin 805. The positioning pin 805 moves away from the pin hole on the pushing cross beam 5, unlocking the pushing seat 7. The pushing seat 7 slides on the sliding groove 6. When the pushing seat 7 slides to the predetermined position, release the hand pull rod 804. The return spring 806 provides elastic potential energy to pull down the positioning plate 803 for resetting, and reinsert the positioning pin 805 into the pin hole on the pushing cross beam 5 to complete the installation limit.
