Description

Technical Field

[0001] The utility model belongs to the field of coal mining equipment, in particular to a transfer machine pushing device for coal mines. Background Art

[0002] In the process of coal mining, the transfer machine, as an important part of the conveying system, is used to transport coal from the excavation face to the transportation system and then to the ground.

[0003] With the increase in mining depth and the development of technology, higher requirements are placed on the mobility and work efficiency of the transfer machine. When pushing the transfer machine, due to uneven ground or excessive load, the existing support structure may not provide sufficient stability, which may easily cause the machine to shake or overturn. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a coal mine transfer machine pushing device.

[0005] The utility model is implemented by the following technical scheme: a transfer machine pushing device for coal mines, including a transfer machine body, a connecting block is fixedly connected to the lower surface of the transfer machine body, a supporting cross frame is fixedly connected to the lower surface of the connecting block, and a reinforcing beam is fixedly connected to the lower surface of the supporting cross frame.

[0006] Among them, by setting connecting blocks and supporting cross frames under the transfer machine body, the contact area between the equipment and the ground can be increased, thereby improving the stability and safety of the device. The setting of reinforced beams can enhance the overall bearing capacity of the supporting structure, allowing the transfer machine to withstand larger loads and be suitable for larger-scale coal mine production.

[0007] The lower surface of the reinforcement beam is fixedly connected to a first base frame, and the outer surface of the first base frame is fixedly connected to a second base frame. The arrangement of the first base frame and the second base frame can disperse the pressure on the reinforcement beam, extend its service life, and reduce the risk of damage caused by long-term concentrated pressure. The design of the two-layer base frame enhances the bearing capacity and stability of the entire device, so that the device can support heavier loads and meet the needs of larger-scale coal mining.

[0008] Wherein, both sides of the upper surface of the second chassis are fixedly connected with positioning supports, and the outer surface of the positioning supports is fixedly connected with auxiliary blocks. Through the above technical solution, the positioning supports can provide accurate positioning for the coal mine transfer machine, ensure that it maintains the correct direction and position during the moving process, and improve work efficiency.

[0009] Among them, the surfaces of the positioning support and the auxiliary block are provided with sockets. Due to the use of a mechanically fixed connection method, compared with pure welding or other temporary fixing methods, this design is more durable and suitable for long-term use in harsh underground coal mine environments.

[0010] The socket is provided with a latch pin, one end of which is threadedly connected with a hexagonal bolt. Through the above technical solution, a more stable fixing method can be achieved by connecting the latch pin and the hexagonal bolt, thereby avoiding loosening under heavy load or vibration environment, thereby ensuring the stability of the entire device.

[0011] The upper surface of the second chassis is fixedly connected with a push rod, and the outer surface of the push rod is sleeved with an anti-slip sleeve. The function of the push rod is to provide a stable hand-holding position for the operator to control the moving direction of the entire coal mine transfer machine pushing device.

[0012] The lower surface of the first chassis is fixedly connected with a moving wheel, and the lower surface of the second chassis is fixedly connected with a driving motor. The moving wheels are installed on the lower surface of the first chassis, which can greatly reduce the friction resistance of the device when it moves on the ground, making the pushing process easier. By using the moving wheels, the operator does not need to directly lift the loader, but only needs to cooperate with the driving wheels to achieve position adjustment, which greatly reduces physical exertion and improves work efficiency.

[0013] The output end of the driving motor is fixedly connected to a linkage shaft, and driving wheels are arranged at both ends of the linkage shaft. The driving motor can efficiently transmit power to the driving wheels on both sides through the setting of the linkage shaft. Since the front side is also equipped with a moving wheel, a complete power transmission chain is formed, so that the whole device has the ability to move autonomously, so that the user does not need to perform the pushing and pulling operation personally.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model provides a driving motor, and the driving motor can efficiently transmit power to the driving wheels on both sides through a linkage shaft. Because the moving wheels are also installed on the front side, a complete power transmission chain is formed, so that the whole device has the ability to move independently. In this way, the user does not need to perform pushing and pulling operations personally. The supporting cross frame and the reinforcement beam strengthen the bottom supporting structure of the transfer machine body, improve the overall stability and carrying capacity, reduce the risk of deformation or damage that may occur during the pushing process, and improve the safety of coal mine production. In addition, the push rod makes it easy for auxiliary personnel to control the moving direction of the whole device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Please combine Figure 1-4 A coal mine transfer machine pushing device of the present embodiment includes a transfer machine body 1, a connecting block 2 is fixedly connected to the lower surface of the transfer machine body 1, a supporting cross frame 3 is fixedly connected to the lower surface of the connecting block 2, and a reinforcing beam 4 is fixedly connected to the lower surface of the supporting cross frame 3. During operation, the connecting block 2, the supporting cross frame 3 and the reinforcing beam 4 together constitute a stable supporting structure, which is fixedly connected to the bottom of the transfer machine body 1, providing additional supporting force and stability for the transfer machine, thereby preventing the machine from being unstable or overturned due to excessive load or uneven ground during the pushing process.

[0024] In this embodiment, the lower surface of the reinforcement beam 4 is fixedly connected to the first base frame 5, and the outer surface of the first base frame 5 is fixedly connected to the second base frame 6. The connection between the first base frame 5 and the second base frame 6 is a side fixed connection. This structure can provide lateral support to prevent the device from tipping over or tilting during the pushing process, thereby ensuring the stability of the device in the horizontal direction.

[0025] In this embodiment, positioning supports 7 are fixedly connected to both sides of the upper surface of the second base frame 6, and auxiliary blocks 8 are fixedly connected to the outer surfaces of the positioning supports 7. Personnel connect the auxiliary blocks 8 to the transfer machine body 1, and then connect the auxiliary blocks 8 and the positioning supports 7 through the latches 9.

[0026] In this embodiment, the surfaces of the positioning support 7 and the auxiliary block 8 are provided with insertion holes. The positioning support 7 and the auxiliary block 8 are designed to enhance the stability of the transfer machine body 1 during the pushing process. They play the role of auxiliary support. By connecting with the transfer machine body 1, unnecessary movement that may occur during the pushing of the transfer machine is limited, thereby ensuring the safety of the operation.

[0027] In this embodiment, a latch 9 is provided inside the socket, and one end of the latch 9 is threadedly connected with a hexagonal bolt 10. The function of the latch 9 is to fix the positioning support 7 and the auxiliary block 8 together. By inserting them into the corresponding sockets of both parties, the relative movement of the two can be restricted, so that the auxiliary block 8 and the positioning support 7 form a stable supporting structure. The hexagonal bolt 10 is used to further tighten the latch 9. When the latch 9 is inserted into the socket, the latch 9 can be tightly fixed in the socket by rotating the hexagonal bolt 10.

[0028] In this embodiment, a push rod 11 is fixedly connected to the upper surface of the second base frame 6, and an anti-slip sleeve 12 is sleeved on the outer surface of the push rod 11. The function of the push rod 11 is to provide an operator with a stable hand-holding position to control the moving direction of the entire coal mine transfer machine pushing device. The fixed connection of the push rod 11 ensures the stable transmission of thrust, making the operation more labor-saving and efficient. The anti-slip sleeve 12 sleeved on the push rod 11 can increase the friction between the operator's hand and the push rod 11, avoiding hand slips in a humid or greasy environment, thereby improving the safety of operation.

[0029] In this embodiment, the lower surface of the first base frame 5 is fixedly connected with a moving wheel 13, and the lower surface of the second base frame 6 is fixedly connected with a driving motor 14. Installing the moving wheel 13 on the lower surface of the first base frame 5 can greatly reduce the friction resistance of the device when moving on the ground, making the pushing process easier. By using the moving wheel 13, the operator does not need to directly lift the loader, but only needs to cooperate with the driving wheel 16 to achieve position adjustment, which greatly reduces physical exertion and improves work efficiency.

[0030] In this embodiment, the output end of the driving motor 14 is fixedly connected to the linkage shaft 15, and driving wheels 16 are provided at both ends of the linkage shaft 15. The driving motor 14 can efficiently transmit power to the driving wheels 16 on both sides through the setting of the linkage shaft 15. Since the moving wheel 13 is also installed on the front side, a complete power transmission chain is formed, so that the whole device has the ability to move autonomously, so that the user does not need to perform pushing and pulling operations personally.

[0031] In actual application, first, fix the connecting block 2 on the lower surface of the transfer machine body 1, then fix the supporting cross frame 3 on the connecting block 2, and fix the reinforcing beam 4 on the lower surface of the supporting cross frame 3. The reinforcing beam 4 plays the role of strengthening support and transferring load. Fix the first base frame 5 on the lower surface of the reinforcing beam 4, and fix the second base frame 6 on the outer surface of the first base frame 5 to provide lateral support and enhance the stability of the device. Install the positioning support 7 on both sides of the upper surface of the second base frame 6, and fix the auxiliary block 8 thereto, use the latch 9 to connect the auxiliary block 8 and the positioning support 7, and further tighten the latch 9 by rotating the hexagonal bolt 10 to form a stable supporting structure, fix the push rod 11 on the upper surface of the second base frame 6, and cover the anti-slip cover 12 on its outer surface. The operator can By holding the anti-slip sleeve 12 to push the push rod 11, a good grip can be guaranteed even when the hands are sweating or the ground is wet, ensuring the safety and accuracy of the operation. When the transfer machine body 1 needs to be moved, the drive motor 14 is started. The drive motor 14 can efficiently transmit power to the drive wheels 16 on both sides through the setting of the linkage shaft 15. Since the front side is also equipped with a moving wheel 13, a complete power transmission chain is formed, so that the entire device has the ability to move independently. The operator can use the push rod 11 to assist in controlling the moving direction. The push rod 11 passes through the positioning support 7 on the second base frame 6. Since the auxiliary block 8 is connected to the positioning support 7, the auxiliary block 8 is connected to the transfer machine body 1, so that the moving direction of the transfer machine body 1 can be controlled to the specified position.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
