Description

Technical Field

[0001] The utility model relates to the technical field of support net connection, in particular to a high-strength mining support net connection auxiliary tooling. Background Art

[0002] The coal mine support and protection net is a structural material used to support tunnels and prevent rock collapse during underground coal mining. It plays a role in fixing rock formations, preventing collapses, and protecting the safety of miners in coal mining projects. The space inside the mine tunnel is large, and the support net is produced in fixed sizes during production. Therefore, before the support net is transported into the mine tunnel, it is necessary to connect several support nets into a whole so that it can adapt to the size of the internal space of the mine tunnel and reduce the number of connections in the mine tunnel. The current common method is to lay several support nets flat on the ground, and then the staff will bundle and connect two adjacent support nets. This method requires the staff to squat on the ground for a long time to operate, which not only has low work efficiency, but also low operating comfort. In the long run, it will have an impact on the physical condition of the staff. Utility Model Content

[0003] In order to solve the technical problems of inconvenient support net connection and low operating comfort for workers in the above-mentioned background technology, the utility model provides a high-strength mining support net connection auxiliary tooling.

[0004] The technical solution of this utility model is as follows:

[0005] A high-strength mining support net connection auxiliary tooling includes two slide rails arranged in parallel and a support frame slidingly arranged above them; the support frame includes a plurality of arched rods arranged in parallel along the length direction of the slide rails, and the two ends of the arched rods are respectively slidably connected to the two slide rails; a plurality of sliding rods are inserted into the outer side of the arched rods along the length direction thereof, and the outer ends of the plurality of sliding rods are arranged to be able to pass through the mesh of the support net.

[0006] A support net is laid from one side of the support frame, with the mesh holes on its edge passing through the sliding rods above the arch rods. Another support net is laid from the other side of the support frame, with the mesh holes on its edge passing through the sliding rods above the arch rods. At this time, the two support nets that need to be connected are laid on the support frame in sequence, and the overlapping parts of the two support nets are located between the two arch rods and supported by the arch rods. The staff can connect the two support nets in a sitting position, and no longer need to squat on the ground for a long time to work, which saves time and effort and is convenient to operate. Moreover, the arch rod can slide freely. If the connection size of the support net is large, it can facilitate the segmented connection of the support net. After completing the connection of a certain section, the arch rod can be moved to the connection position of the next section of the support net.

[0007] Furthermore, at least one of the sliding rods is located above the arch rod, which can reduce the arch height of the arch rod while ensuring that the connecting parts of the two protective nets can be completely laid above the support frame, thereby saving materials and space.

[0008] As a preferred embodiment, the arched rod is provided with a through hole extending through both its inner and outer sides, and the sliding rod is slidably disposed within the through hole; the length of the sliding rod is greater than the length of the through hole. When the support net needs to be fixed, the sliding rod can be pushed to the outside of the arched rod and passed through the mesh of the support net to restrict the movement of the support net; when the arched rod needs to be moved, the sliding rod can be pushed to the inside of the arched rod. At this time, the outside of the arched rod no longer restricts the support net, ensuring that the arched rod can move smoothly under the support net.

[0009] Specifically, the sliding rod includes a main rod and blocks at both ends thereof. A recess that can engage with the block is provided in the through hole. The cooperation between the block and the recess can limit the sliding rod and prevent it from falling out of the through hole.

[0010] Further preferably, the clamping block is elastically and retractably arranged to ensure that the sliding rod can slide smoothly in the through hole.

[0011] As a preferred embodiment, the slide rail is further provided with a driving mechanism capable of driving the arch rod to move along the slide rail. The arch rod is driven to move by the driving mechanism without the need for manual pushing by an operator, which saves time and effort and facilitates operation.

[0012] Furthermore, the driving transmission mode of the driving mechanism is screw transmission, which has the characteristics of simple structure, smooth transmission and no noise.

[0013] In order to save space and increase space utilization, the two ends of the arch rod are slidably connected to the slide rail through a connecting seat, and the arch rod is hingedly connected to the connecting seat. When there is no need to connect the support net, the arch rod can be laid down to the ground along the hinge point, saving space and facilitating subsequent stacking of items or other work.

[0014] Through the above design, the beneficial effects of the utility model high-strength mining support net connection auxiliary tooling are:

[0015] (1) By using the arch rod and the sliding rod in conjunction, the parts of the two support nets that need to be connected are erected to a certain height. The operator can perform the connection work in a sitting position and no longer needs to squat on the ground for a long time, which saves time and effort and is convenient for operation.

[0016] (2) When not in use, the arched rod can be laid on the ground to save space and facilitate subsequent stacking of items or other work. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] Combine Figures 1 to 5 This embodiment provides an auxiliary tooling for connecting a high-strength mining support net 5, including two slide rails 1 arranged in parallel, and a support frame 2 slidingly arranged above them; the support frame 2 includes a plurality of arched rods 21 arranged in parallel along the length direction of the slide rails 1, and its two ends are respectively slidably connected to the two slide rails 1.

[0027] In order to save space and increase space utilization, the slide rail 1 is embedded in the ground, and the two ends of the arch rod 21 are slidably connected to the slide rail 1 through the connecting seat 4. The arch rod 21 is hingedly connected to the connecting seat 4. When there is no need to connect the support net 5, the arch rod 21 can be laid down to the ground along the hinge point, saving space and facilitating subsequent stacking of items or other work.

[0028] Combine Figure 3 In a specific implementation, the slide rail 1 includes a rail 11 embedded in the ground, and a groove is provided above the rail 11 along its length direction. The connecting seat 4 is slidably provided in the groove and can slide along the length direction of the groove. The two ends of the arch rod 21 are respectively hingedly connected to the top of the two connecting seats 4, and a locking mechanism is also provided at the hinge to prevent the arch rod 21 from tipping over during use.

[0029] As a preferred embodiment, the slide rail 1 is further provided with a driving mechanism capable of driving the arch rod 21 to move along the slide rail. The arch rod 21 is driven to move by the driving mechanism without the need for manual pushing by the operator, which saves time and effort and facilitates operation.

[0030] Furthermore, the driving transmission mode of the driving mechanism is screw 3 transmission, the screw 3 is arranged in the groove, and the connecting seat 4 is sleeved on the outer ring of the screw 3 and is connected to the screw 3. The screw 3 transmission mode has the characteristics of simple structure, smooth transmission and no noise.

[0031] In this embodiment, a plurality of sliding rods 22 are inserted into the outer side of the arch rod 21 along its length direction, and the outer ends of the plurality of sliding rods 22 are configured to pass through the mesh of the support net 5 .

[0032] Furthermore, at least one of the sliding rods 22 is located above the arch rod 21, which can reduce the arch height of the arch rod 21 while ensuring that the connection parts of the two protective nets 5 can be completely laid above the support frame 2, thereby saving materials and space.

[0033] It is worth noting that there is another possibility for the positions of several of the sliding rods 22, that is, several of the sliding rods 22 are located on the same side of the arch rod 21. When the connection range of the two protective nets 5 is small, the sliding rods 22 on the same side can complete the support and limiting functions, which can reduce the size of the arch rod 21 and the distance between the two slide rails 1, saving space.

[0034] As a preferred embodiment, combined with Figure 2 The arched rod 21 is provided with a through hole 23 extending through both its inner and outer sides, and the sliding rod 22 is slidably disposed within the through hole 23; the length of the sliding rod 22 is greater than the length of the through hole 23. When the support net 5 needs to be fixed, the sliding rod 22 can be pushed to the outside of the arched rod 21 and passed through the mesh of the support net 5 to restrict the movement of the support net 5; when the arched rod 21 needs to be moved, the sliding rod 22 can be pushed to the inside of the arched rod 21. At this time, the outside of the arched rod 21 no longer restricts the support net 5, ensuring that the arched rod 21 can move smoothly under the support net 5.

[0035] Specifically, combined Figure 4 The sliding rod 22 includes a main rod 221 and blocks 222 at both ends thereof. A recess that can be engaged with the block 222 is provided in the through hole 23. The cooperation between the block 222 and the recess can limit the sliding rod 22 and prevent it from falling out of the through hole 23.

[0036] Further preferably, the block 222 is elastically and retractably arranged to ensure that the sliding rod 22 can slide smoothly in the through hole 23 .

[0037] In a specific implementation, the two ends of the main body rod 221 are provided with connecting holes perpendicular to the length direction of the main body rod 221, and the clamping block 222 includes a spring arranged in the connecting hole, and the two ends of the spring are respectively connected to the clamping joints. When the spring is relaxed, the two clamping joints can extend out of the connecting hole and engage with the notch.

[0038] Exemplarily, the recess is configured to be in an arc shape, and the side of the clip joint facing the recess is also configured to be in an arc shape, and the radius of the recess is slightly larger than the radius of the arc side of the clip joint. While ensuring that the recess can limit the main body rod 221, it also ensures that when the main body rod 221 is subjected to a large thrust, the clip joint can be retracted into the connecting hole to complete the sliding of the sliding rod 22 in the through hole 23.

[0039] Combine Figure 5 When in use, first lay one support net 5 from one side of the support frame 2, so that the mesh holes on its edge pass through the sliding rods 22 above the arch rod 21. Then lay another support net 5 from the other side of the support frame 2, and similarly, so that the mesh holes on its edge pass through the sliding rods 22 above the arch rod 21. At this time, the two support nets 5 to be connected are laid on the support frame 2 in sequence, and the overlapping parts of the two support nets 5 are located between the two arch rods 21 and supported by the arch rod 21. The staff can connect the two support nets 5 in a sitting position, and no longer need to squat on the ground for a long time, which saves time and effort and is convenient to operate. Moreover, the arch rod 21 can slide freely. If the connection size of the support net 5 is large, it can facilitate the segmented connection of the support net 5. When a certain section is connected, the sliding rod 22 is first pushed to the inside of the arch rod 21. At this time, there is no obstruction above the arch rod 21, and then the arch rod 21 is moved to the next section of the support net 5.

[0040] The utility model high-strength mining support net 5 connection auxiliary tooling uses the arch rod 21 and the sliding rod 22 to set up the parts of the two support nets 5 to be connected to a certain height. The operator can perform the connection work in a sitting position, no longer needing to squat on the ground for a long time, saving time and effort and facilitating operation. When idle, the arch rod 21 can be laid on the ground to save space and facilitate subsequent stacking of items or other work.
