Description

Technical Field

[0001] This utility model relates to the technical field of slope protection net production equipment, specifically to a pressing mechanism for an active slope protection net locking mechanism. Background Technology

[0002] Slope protection netting is a widely used protective facility in infrastructure construction such as highways, railways, mines, and water conservancy and hydropower projects. Its main function is to prevent weathering, erosion, collapse, and rockfall on slopes. Slope protection netting mainly consists of steel wire ropes and locking clips. Since a single steel wire rope is typically laid in an interlaced mesh on a winding device, locking clips are needed to secure the mesh at the intersections. The existing locking clip installation method is as follows: place the upper locking clip (located above the mesh wire rope) at the intersection of the steel wire ropes, then hold the lower locking clip below the mesh wire rope, directly below the upper locking clip. Finally, a special pressing tool is used to press both clips into place.

[0003] like Figure 1 The diagram shows the structure of a currently used specialized pressing tool. It includes a frame, a platform at the bottom of the frame for placing the lower locking buckle, and a hydraulic cylinder mounted on top of the frame. A pressure plate is mounted with the cylinder's telescopic head facing downwards, and the pressure plate faces the platform. In use, the specialized pressing tool (a small tool) is held in the grid space, and the pressure plate is moved above the grid's intersection point. The upper locking buckle is then aligned at the intersection point, and the lower locking buckle is aligned on the platform. The hydraulic cylinder is then activated to complete the pressing process. The currently used upper locking buckle consists of a top plate and four downward-bending insert plates. The lower locking buckle has insertion holes that match the size and position of the insert plates. The pressing tool is used to press the upper and lower parts together, causing the insert plates to be inserted into the insertion holes and then bend towards the center, thus completing the fixing.

[0004] Currently, the entire pressing process is mainly operated manually. During this process, workers need to place and align the locking buckles one by one, which is tedious and time-consuming. Construction efficiency is still difficult to improve, and the workload of workers is heavy.

[0005] To address the shortcomings of manual operation and reduce the labor intensity of workers, this utility model proposes an automatic pressing device for active slope protection net locking. Summary of the Invention

[0006] The purpose of this utility model is to provide a pressing mechanism for active slope protection net locking buckles, which eliminates the need for manual alignment and adjustment of the upper and lower locking buckles, reducing the labor intensity of workers and improving pressing efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A pressing mechanism for an active slope protection net locking device includes a support plate. The support plate has a storage device and a pressing device at its bottom. The storage device includes a hollow storage box and an inclined plate. The storage box has an inlet at its upper part and an outlet at its lower part. The left end of the inclined plate is connected to the outlet of the storage box, and the left end of the inclined plate is higher than its right end. A vertical plate is also provided at the bottom of the support plate, positioned between the storage device and the pressing device. The lower part of the vertical plate has a through hole communicating with the right end of the inclined plate. The pressing device... The device includes an upper pressing assembly, a lower pressing assembly, and a hydraulic cylinder. The hydraulic cylinder is fixedly connected to the bottom of a support plate. The top of the upper pressing assembly is fixedly connected to the telescopic end of the hydraulic cylinder. The upper pressing assembly includes an upper pressing plate with a first contouring groove that matches the shape of the top of an upper locking buckle. The left end of the lower pressing assembly is fixedly connected to the bottom of a vertical plate. The lower pressing assembly includes a lower pressing plate with a second contouring groove that matches the shape of a lower locking buckle. The first contouring groove is located directly above the second contouring groove.

[0009] As a preferred technical solution, the support plate is provided with two lifting rings at the top, and the support plate is connected to the spring crane through the lifting rings.

[0010] As a preferred technical solution, the internal cavity of the storage box is the same as the lower locking structure.

[0011] As a preferred technical solution, the bottom of the cavity inside the storage box is inclined, and the side of the bottom of the cavity near the inclined plate is lower than the side away from the inclined plate.

[0012] As a preferred technical solution, the bottom of the upper pressure plate is also provided with a guide component for aligning the upper lock. The guide component includes four arc-shaped guide blocks, which are arranged around the first contour groove. The guide blocks have inclined surfaces at both ends, which slope from the middle to both ends, and the lower end of the inclined surface is located at the groove edge of the first contour groove.

[0013] As a preferred technical solution, a number of ball bearings are embedded on the inclined surface of the guide block.

[0014] As a preferred technical solution, the bottom of the second contour groove is provided with a guide groove, and the top diameter of the guide groove is larger than the bottom diameter.

[0015] As a preferred technical solution, a connecting groove is provided on the lower pressure plate, one end of the connecting groove is connected to the through hole of the vertical plate, and the other end of the connecting groove is connected to the second contour groove.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] In this invention, a storage box equipped with a lower locking buckle can hold multiple lower locking buckles at once. The lower locking buckles can be automatically discharged to the pressing position of the lower pressure plate, avoiding the need to remove the lower locking buckles every time pressing is performed, thus reducing the workload of workers.

[0018] In this invention, a first contouring groove is provided on the upper pressure plate, which matches the shape of the top of the upper latch. A second contouring groove is provided on the lower pressure plate, which matches the shape of the lower latch. When the top of the upper latch is engaged in the first contouring groove and the lower latch is engaged in the second contouring groove, the insertion plate of the upper latch matches the insertion hole of the lower latch. The hydraulic cylinder drives the upper latch to descend, and the insertion plate of the upper latch can be smoothly inserted into the insertion hole of the lower latch. Furthermore, a guide assembly is provided on the upper pressure plate, comprising four guide blocks. Positioned around the first contour groove, when the upper locking buckle is misaligned with the first contour groove, the guide block allows the upper locking buckle to rotate slightly. After rotation, the upper locking buckle can smoothly engage in the first contour groove, eliminating the need for manual alignment. Furthermore, since the lower locking buckle has only one placement direction in the second contour groove, and this placement direction is the same as its placement direction in the storage box, the lower locking buckle, after leaving the storage box, can slide directly into the second contour groove via the inclined plate, maintaining its position, and engage in the second contour groove, again eliminating the need for manual alignment. This ensures that the entire pressing process requires no manual alignment of the upper and lower locking buckles, and relies on the limiting effect of the first and second contour grooves to ensure smooth pressing of the upper and lower locking buckles.

[0019] The lower pressure plate is provided with a guide groove, which allows the upper locking plate to tilt and bend along the guide groove when the upper locking buckle descends, ensuring successful installation of the upper and lower locking buckles.

[0020] In this invention, an automatic pressing mechanism is connected to a spring crane, so that when moving from one work point to the next, there is no need for manual hand-moving. The automatic pressing mechanism can be pulled to the corresponding work point when necessary, which is more convenient for workers. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Example

[0034] like Figure 2-6 As shown, a pressing mechanism for an active slope protection net locking buckle includes a support plate 1. The bottom of the support plate 1 is provided with a storage device and a pressing device. The storage device stores the lower locking buckle 8, and during pressing, the lower locking buckle 8 is continuously sent into the pressing device. The pressing device fixes the upper locking buckle 7 and the lower locking buckle 8 onto the slope protection net 6.

[0035] The storage device includes a hollow storage box 2 and an inclined plate 22. The upper part of the storage box 2 has an inlet 21 and the lower part has an outlet. The left end of the inclined plate 22 is connected to the outlet of the storage box 2. The left end of the inclined plate 22 is higher than the right end of the inclined plate 22. The lower locking buckle 8 can be inserted into the storage box 2 from the inlet 21. Multiple lower locking buckles 8 can be inserted at one time to avoid having to remove the lower locking buckle 8 each time during pressing. The height of the outlet of the storage box 2 is greater than the thickness of one lower locking buckle 8, but less than the sum of the thicknesses of two lower locking buckles 8, so that only one lower locking buckle 8 comes out from the outlet at a time. The lower locking buckle 8 coming out from the outlet slides down the inclined plate 22 and enters the pressing device for pressing.

[0036] Vertical baffles are provided on the front and rear sides of the inclined plate 22 to prevent the lower locking buckle 8 from disengaging from the inclined plate 22 when it slides down.

[0037] Since the outlet height of storage box 2 is higher than the height of one lower latch 8 but lower than the height of the overlap of two lower latches 8, the lower latches 8 inside storage box 2 will come out from the outlet one after another and be arranged on the inclined plate 22. After the pressing of one latch is completed, all the lower latches 8 on the inclined plate 22 will slide down one after another, and another lower latch 8 will come out from storage box 2 to fill the gap.

[0038] A vertical plate 3 is provided between the storage device and the pressing device. The top of the vertical plate 3 is fixedly connected to the support plate 1. A through hole 31 is provided at the bottom of the vertical plate 3, and the through hole 31 is connected to the right end of the inclined plate 22.

[0039] The pressing device includes an upper pressing assembly, a lower pressing assembly, and a hydraulic cylinder 41. The hydraulic cylinder 41 is fixedly connected to the bottom of the support plate 1. The top of the upper pressing assembly is fixedly connected to the telescopic end of the hydraulic cylinder 41. The upper pressing assembly includes an upper pressing plate 4, which has a first contouring groove 42 and a guide assembly. The first contouring groove 42 matches the top shape of the upper locking buckle 7. The left end of the lower pressing assembly is fixedly connected to the bottom of the vertical plate 3. The lower pressing assembly includes a lower pressing plate 5, which has a second contouring groove 51, which matches the shape of the lower locking buckle 8. The first contouring groove 42 is located directly above the second contouring groove 51. When the upper pressing assembly is placed above the upper locking buckle 7, the upper locking buckle 7 is placed at the intersection of the wire ropes. The hydraulic cylinder 41 works to drive the upper pressing assembly to descend. The upper pressing assembly descends and contacts the top of the upper locking buckle 7, causing the upper locking buckle 7 to descend. When the upper locking buckle 7 descends to the bottom of its four insert plates and contacts the lower pressure plate 5, it will be subjected to an upward reaction force, causing the top of the upper locking buckle 7 to insert into the first contouring groove 42. If the upper locking buckle 7 is misaligned with the first contouring groove 42, causing the upper locking buckle 7 to be unable to be directly inserted into the first contouring groove 42, the guiding effect of the guide component will cause the upper locking buckle 7 to rotate slightly to match the position of the first contouring groove 42, and the top of the upper locking buckle 7 will then be inserted into the first contouring groove 42. The lower locking buckle 8 slides from the inclined plate 22 through the through hole 31 on the vertical plate 3 into the second contouring groove 51. When the top of the upper locking buckle 7 is inserted into the first contouring groove 42, and the lower locking buckle 8 is located in the second contouring groove 51, the four insert plates of the upper locking buckle 7 match the positions of the insertion holes on the lower locking buckle 8, and the upper locking buckle 7 descends directly, and the insert plates can be smoothly inserted into the insertion holes without manual positioning.

[0040] It should be noted that the second contour groove 51 can limit the lower locking buckle 8, that is, the lower locking buckle 8 has only one placement direction in the second contour groove 51, and this placement direction is the same as the placement direction of the lower locking buckle 8 in the storage box 2. This allows the lower locking buckle 8 to slide directly into the second contour groove 51 through the inclined plate 22 after leaving the storage box 2. The gap between the front and rear baffles of the inclined plate 22 and the lower locking buckle 8 is very small, so that the lower locking buckle 8 does not shift during the downward movement and can be locked into the second contour groove 51 without misalignment.

[0041] In some feasible embodiments, the support plate 1 is provided with two lifting rings 11 at its top, and the support plate 1 is connected to the spring crane through the lifting rings 11. The spring crane is mainly used in situations where the work position is not fixed, to lift the operating tool, and with the energy stored in the coil spring, the suspended operating tool is in a weightless state. When using it, the worker only needs to pull it down, and after use, he can simply release it, and the operating tool will rise back to its original position under the action of the spring. In this example, the spring crane is used to lift the entire pressing device and suspend it above the main slope protection net. When pressing is to be performed, the worker only needs to pull the device down to the position to be pressed. After pressing is completed, the worker releases it, and the pressing device will rise back to its original position under the action of the spring crane. Moreover, when the worker pulls down the pressing device, the spring crane still plays a lifting role for the pressing device, that is, the worker only needs to provide a small force against the spring and does not need to bear the weight of the entire pressing device.

[0042] It should be noted that the slope protection net 6 is a mesh structure formed by winding steel wire rope around the winding base 9. Slide grooves 91 are provided on opposite sides of the winding base 9. The slide grooves 91 are through grooves, and slide plates 92 can slide within them. Both ends of the slide plates 92 slide within the slide grooves 91 and can be pulled out from one end. The slide plates 92 are located below the wound steel wire rope. During pressing, the lower pressure plate 5 is placed above the slide plates 92. When the hydraulic cylinder 41 presses down to perform the pressing operation, the slide plates 92 provide support for the pressing, ensuring the stability of the hydraulic cylinder 41's pressing action.

[0043] In some feasible embodiments, the internal cavity of the storage box 2 has the same structure as the lower latch 8, so that the lower latch 8 has only one storage direction in the storage box and is placed in the same direction as the second square groove, which makes it easy for the insert plate of the upper latch 7 to be smoothly inserted into the insertion hole of the lower latch 8 during pressing.

[0044] In some feasible embodiments, the bottom of the cavity inside the storage box 2 is inclined, and the side of the bottom of the cavity near the inclined plate 22 is lower than the side away from the inclined plate 22, so that the lower latch 8 can smoothly leave the storage box 2 from the outlet.

[0045] In some feasible embodiments, the guide assembly includes four arc-shaped guide blocks 43, which are arranged around the first contour groove 42. Each guide block 43 has an inclined surface at both ends, sloping from the middle to both ends, with the lower end of the inclined surface located at the edge of the first contour groove 42. When the upper pressure plate 4 is placed above the upper locking buckle 7, and the first contour groove 42 is misaligned with the upper locking buckle 7, the upper pressure plate 4 moves downward under the action of the hydraulic cylinder 41, causing the upper locking buckle 7 to move downward synchronously. When the bottom of the four insert plates of the upper locking buckle 7 contacts the lower pressure plate 5, the upper locking buckle 7 receives an upward reaction force. Since both sides of the guide block 43 are inclined, this reaction force can be decomposed into forces perpendicular to and along the inclined surface. At this time, the upper locking buckle 7 will rotate along the inclined surface of the guide block 43 until it rotates to the bottom of the inclined surface and engages in the first contour groove 42.

[0046] It should be noted that when the upper locking buckle 7 and the lower locking buckle 8 are pressed together, the bottom of the upper pressure plate 4 and the top of the lower pressure plate 5 do not contact each other, and there is a gap between the upper pressure plate 4 and the lower pressure plate 5. This gap is greater than the height of the guide block 43, so that the guide block 43 will not contact the lower pressure plate 5 and will not interfere with the pressing of the locking buckle. At the same time, since the lower locking buckles 8 are arranged one after another on the inclined plate 22, when the lower locking buckle 8 located in the second contour groove 51 is pressed together, due to the existence of the above-mentioned gap, the next lower locking buckle 8 will not contact the upper pressure plate 4 and will not interfere with the pressing of the locking buckle.

[0047] In some feasible embodiments, a plurality of balls 44 are embedded on the inclined surface of the guide block 43. The balls 44 reduce the friction between the locking buckle 7 and the inclined surface of the guide block 43, so that the locking buckle 7 can rotate and engage more smoothly into the first contour groove 42.

[0048] In some feasible embodiments, the bottom of the second contour groove 51 is provided with a guide groove 52. The top diameter of the guide groove 52 is larger than the bottom diameter. After the insert plate of the upper latch 7 passes through the insertion hole of the lower latch 8, the bottom of the insert plate directly contacts the side wall of the guide groove 52. Under the guiding action of the inclined surface of the guide groove 52, the lower end of the insert plate will tilt towards the center. At this time, the hydraulic cylinder 41 continues to work, driving the upper latch 7 to continue downward until the lower end of the insert plate bends towards the center.

[0049] In some feasible embodiments, a connecting groove 53 is provided on the lower pressure plate 5. One end of the connecting groove 53 is connected to the through hole 31 of the vertical plate 3, and the other end of the connecting groove 53 is connected to the second contour groove 51, so that the lower locking buckle 8 can smoothly slide from the inclined plate 22 into the second contour groove 51.
