Technical Field

[0001] The invention relates to the technical field of stone slab hangers, in particular to a hanger for laying polygonal edge block stone slabs for slope protection. Background Art

[0002] Slope protection can effectively protect the ecological environment and prevent slope damage and soil erosion caused by natural or human factors. It is not only conducive to maintaining ecological balance, but also can reduce land degradation, and can also prevent landslides, thus ensuring traffic safety. In the process of slope protection, polygonal edged stone slabs are needed. The reasonable laying of polygonal edged stone slabs can enhance the stability of protection and prevent rainwater from eroding the soil. When polygonal edged stone slabs are used, stone slab hoists are needed. For example, a stone slab lifting device with publication number CN208361696U includes a lifting beam, wherein at least two sliding seats that can slide along the length of the lifting beam are sleeved on the upper part of the lifting beam, a guide structure that can limit the vertical direction of the two is provided between the sliding seat and the lifting beam, and a positioning mechanism that fixes the two is also provided between the sliding seat and the lifting beam; a lifting rope and a sling that can be sleeved on the plate are passed through the sliding seat. This stone slab lifting device can adjust the interval between the two sliding seats so that the sling can sleeve plates of different lengths, has good adaptability and is easy to adjust; the sliding seat is firmly connected to the lifting beam, and the lifting is safe, and it is easy to connect or disassemble and replace; it can lift plates of different widths and has a wide range of applications; Another example is a stone slab hanger with publication number CN211945910U, which includes a hanger body, the hanger body includes side brackets located on both sides, a crossbeam fixedly connected between the side brackets on both sides, a sliding frame vertically slidably arranged between the side brackets on both sides, and a clamping plate fixedly arranged on the two sliding frames, the two clamping plates are arranged opposite to each other, and the opposite surfaces of the two clamping plates have a mesh structure, and an adjustment mechanism is arranged between the sliding frames on both sides and the crossbeams on the corresponding sides, and a stabilizing ring in the shape of an isosceles triangle and made of hard metal is arranged on the upper part of the hanger body, and the two bottom corners of the stabilizing ring are respectively connected to the upper ends of the side brackets on both sides by connecting traction ropes, and the top corners of the stabilizing ring are connected to the lifting rope; There is also a kind of artificial granite plate packing lifting device with publication number CN213202079U, which includes a lifting module, a moving module and an adjustment module. The lifting module includes a U-shaped lifting arm, and a toothed plate is fixedly connected to the side wall of one end of the U-shaped lifting arm, and the moving module includes a moving frame. Through the setting of bevel gear 1, bevel gear 2 and semicircular rod, the horizontal displacement of the moving frame on the U-shaped lifting arm is adjusted, thereby adjusting the horizontal position of the artificial granite. Through the setting of the moving plate, the moving bevel gear and the bevel toothed plate on the annular lifting arm, the angle of the annular lifting arm is adjusted, thereby adjusting the placement angle of the artificial granite. Through the setting of the clamping block and the moving plate, the switching between adjusting the horizontal position of the artificial granite and adjusting the placement angle is achieved, which is convenient for the staff in the carriage to operate and adjust, and is convenient for the placement of the artificial granite, thereby improving the packing efficiency of the artificial granite. During use, the staff needs to place the number of stone slabs according to the actual situation. However, the device in the above application does not have a structure for adjusting the storage size of the sling according to the actual situation, which leads to a small overall use range of the device and great limitations in use. At the same time, during use, when the gravity of a single transport is too heavy, there will be safety hazards. During use, the device in the above application does not have an overload reminder structure, which leads to low overall safety of the device, causing unnecessary trouble to the operator.

[0003] In view of the above problems, it is urgent to carry out innovative design based on the original stone slab hanger. Summary of the invention

[0004] The object of the present invention is to provide a sling for laying polygonal edge stone slabs for slope protection, so as to solve the problem proposed in the above-mentioned background technology that during use, there is no structure for adjusting the storage size of the sling according to actual conditions, which leads to a small range of use of the entire device, great limitations during use, and during use, there is no overload reminder structure, so that the overall safety of the device is low, which brings unnecessary troubles to the operator.

[0005] To achieve the above object, the present invention provides the following technical solution: a hanging device for laying polygonal slabs for slope protection, comprising a fixed plate and a connecting shaft, a surface of the fixed plate is fixedly connected with a long pin, and the long pin is symmetrically distributed about the center of the fixed plate, and the surface of the long pin is sleeved and connected with an extrusion plate; A handle is fixedly connected to the left end of the connecting shaft, and the connecting shaft passes through the interior of the fixing plate and the extrusion plate; A sling for laying polygonal slabs for slope protection, further comprising: A limit plate, the limit plate is fixedly connected to the right side of the long pin; A limiting rod, wherein the limiting rod is slidably arranged inside the fixing plate, and the limiting rod passes through the inside of the fixing plate, and a placement groove is provided on the surface of the fixing plate; A hook, the hook is fixedly arranged on the outer side of the fixing plate and the outer side of the extrusion plate, and the hook is an inverted "L" structure when viewed from the side; A baffle, the baffle is clamped and arranged inside the fixed plate, and the end of the baffle is movably arranged inside the long groove; A protection frame, wherein the protection frame is fixedly connected to the upper surface of the limiting plate, and a lap block is fixedly connected to the upper surface of the limiting plate, and the lap block is located outside the protection frame; The copper sheet is fixedly connected to the inside of the protection frame, and a partition net is fixedly connected to the surface of the protection frame.

[0006] Preferably, the middle portion of the connecting shaft to the right side is threadedly connected to the extrusion plate, and the surface of the extrusion plate is provided with long grooves corresponding to the placement grooves one by one.

[0007] Preferably, a limiting groove corresponding to the limiting rod is formed on the surface of the baffle, and a protrusion is fixedly connected to the surface of the limiting rod, and the protrusions are symmetrically distributed about the center of the limiting rod.

[0008] Preferably, the interior of the fixing plate is provided with grooves corresponding to the protrusions one by one, and the surface of the protrusion is fixedly connected to a first spring that plays an elastic reset role, and the other side of the first spring is fixedly connected to the interior of the fixing plate.

[0009] Preferably, both upper and lower sides of the limit rod are inclined.

[0010] Preferably, a pressure-bearing rod is slidably arranged inside the overlap block, and a blocking piece is fixedly connected to the end of the pressure-bearing rod, and the overlap blocks are symmetrically distributed about the center of the limiting plate.

[0011] Preferably, a knocking rod is slidably provided inside the overlap block, and the end of the knocking rod is fixedly connected to an auxiliary plate, and the surface of the knocking rod is fixedly connected to a force-bearing plate.

[0012] Preferably, an auxiliary rod is fixedly connected to the end of the other side of the pressure-bearing rod, and the auxiliary rod is an inverted "L" structure when viewed from above, and the auxiliary rod is initially in contact with the inner wall of the auxiliary plate.

[0013] Preferably, a return spring having an elastic return function is fixedly connected to the surface of the force-bearing plate, and the other side of the return spring is fixedly connected to the surface of the overlap block.

[0014] Preferably, a second spring having an elastic reset function is fixedly connected to the surface of the blocking piece, and the other side of the second spring is fixedly connected to the surface of the overlapping block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the sling for laying polygonal slabs for slope protection adopts a new structural design, so that when the device is used once, the spacing between the extrusion plate and the fixed plate can be controlled according to the actual number, so that the stones can be kept stable. At the same time, an overweight sound reminder structure is provided, which improves the overall safety of the device. The specific contents are as follows: (1) During use, the handle and the connecting shaft of the sling for laying polygonal slabs for slope protection can be rotated so that the connecting shaft drives the extrusion plate to slide on the long pin, thereby controlling the distance between the extrusion plate and the fixed plate. That is, the operator can control the number of slabs actually placed, thereby improving flexibility and convenience. Furthermore, after the stone slab is placed, a baffle can be inserted into the placement slot, and the limit rod will enter the limit slot. At this time, the baffles on the left and right sides play a limiting role, so that the stone will not fall; Furthermore, the limiting rod and the limiting groove enable the baffle to move only in the vertical direction, so that when the device as a whole is hoisted, the baffle will not slide down. When the baffle needs to be pulled out in the horizontal direction, the limiting rod can be pulled so that the limiting rod drives the protrusion to squeeze the first spring and the end of the limiting rod moves out of the limiting groove. At this time, the baffle can be pulled in the horizontal direction, which is convenient for the user to operate. (2) The sling used for laying the polygonal edge stone slabs for slope protection, initially, the surface of the auxiliary rod fits with the surface of the auxiliary plate, and the auxiliary plate is supported by the auxiliary rod. In the process of placing stones, when the staff adjusts the position of the extrusion plate according to the actual situation, the right side of the extrusion plate may contact the baffle. At this time, the baffle moves in the direction of the second spring. At the same time, when the baffle moves, it will drive the pressure rod and the auxiliary rod to move synchronously. When the auxiliary rod does not contact the auxiliary plate, the auxiliary plate drives the knocking rod to move inside the protection frame under the action of the reset spring. Finally, the knocking rod will hit the copper sheet on the inner wall of the protection frame, causing the copper sheet to make a sound, which is convenient for reminding the staff to place the stones according to this spacing. The device will eventually be in an overweight state, which improves the overall safety of the device; Furthermore, the partition net on the inner wall of the protection frame prevents the copper sheet from being hit by debris, thereby preventing false ringing, thereby ensuring the accuracy of the sound alarm.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 9 The present invention provides the following technical solution: a hanger for laying polygonal slabs for slope protection: Embodiment 1: By setting the handle 3 and the connecting shaft 4, the distance between the squeezing plate 5 and the fixing plate 1 can be quickly adjusted, so that the operator can place the stone reasonably according to the actual situation, so that the stone can be squeezed by the squeezing plate 5 and the fixing plate 1. Figure 1 and Figure 2 As shown: It includes a fixing plate 1 and a connecting shaft 4, a long pin 2 is fixedly connected to the surface of the fixing plate 1, and the long pin 2 is symmetrically distributed about the center of the fixing plate 1, and a pressing plate 5 is sleeved and connected to the surface of the long pin 2, a handle 3 is fixedly connected to the left end of the connecting shaft 4, and the connecting shaft 4 runs through the inside of the fixing plate 1 and the pressing plate 5; A sling for laying polygonal slabs for slope protection, further comprising: A limit plate 9, the limit plate 9 is fixedly connected to the right side of the long pin 2, a limit rod 11, the limit rod 11 is slidably arranged inside the fixed plate 1, and the limit rod 11 penetrates the inside of the fixed plate 1, and a placement groove 6 is opened on the surface of the fixed plate 1; A hook 8, the hook 8 is fixedly arranged on the outer side of the fixed plate 1 and the outer side of the extrusion plate 5, and the hook 8 is an inverted "L" structure when viewed from the side; a baffle 10, the baffle 10 is clamped and arranged inside the fixed plate 1, and the end of the baffle 10 is movably arranged inside the long groove 7; A protective frame 22, the protective frame 22 is fixedly connected to the upper surface of the limiting plate 9, and the upper surface of the limiting plate 9 is fixedly connected with a lap block 25, and the lap block 25 is located on the outside of the protective frame 22, a copper sheet 23, the copper sheet 23 is fixedly connected to the inside of the protective frame 22, and a partition net 24 is fixedly connected to the surface of the protective frame 22, the middle part of the connecting shaft 4 to the right side is threadedly connected to the extrusion plate 5, and the surface of the extrusion plate 5 is provided with a long groove 7 corresponding to the placement groove 6.

[0020] During use, the handle 3 and the connecting shaft 4 can be rotated so that the connecting shaft 4 drives the extrusion plate 5 to slide on the long pin 2, thereby controlling the distance between the extrusion plate 5 and the fixed plate 1, that is, the operator can control the actual number of stones placed, thereby improving flexibility and convenience. At the same time, after placing the stones, the extrusion plate 5 can also be moved so that the extrusion plate 5 and the fixed plate 1 support the stones, thereby ensuring the stability of the stones when being lifted.

[0021] Embodiment 2: Different from Embodiment 1, the baffle 10 is provided to optimize the stability of the stone when it is hoisted. Figure 3-Figure 6 As shown: A limiting groove 12 corresponding to the limiting rod 11 is provided on the surface of the baffle 10, and a protrusion 13 is fixedly connected to the surface of the limiting rod 11, and the protrusions 13 are symmetrically distributed about the center of the limiting rod 11. A groove 14 corresponding to the protrusions 13 is provided inside the fixed plate 1, and a first spring 15 that plays an elastic reset role is fixedly connected to the surface of the protrusion 13, and the other side of the first spring 15 is fixedly connected to the inside of the fixed plate 1, and the upper and lower sides of the limiting rod 11 are both inclined.

[0022] After placing the stone slab, the baffle 10 can be inserted into the placement groove 6. At this time, the limit rod 11 will enter the limit groove 12. At this time, the baffles 10 on the left and right sides play a limiting role, so that the stone will not fall. The limit rod 11 and the limit groove 12 make the baffle 10 only move in the vertical direction, and then when the device is hoisted as a whole, the baffle 10 will not slip. When the baffle 10 needs to be pulled out in the horizontal direction, the limit rod 11 can be pulled to make the limit rod 11 drive the protrusion 13 to slide in the groove 14. At the same time, the protrusion 13 squeezes the first spring 15, and at the same time, the end of the limit rod 11 moves out of the limit groove 12. At this time, the baffle 10 can be pulled in the horizontal direction, which is convenient for the user to operate.

[0023] Embodiment 3: Different from Embodiment 2, the knocking rod 20 and the copper sheet 23 are provided to enable the device to have a sound warning function, thereby avoiding the occurrence of overweight. Figure 7-Figure 9 As shown: A pressure-bearing rod 16 is slidingly arranged inside the overlap block 25, and a baffle 17 is fixedly connected to the end of the pressure-bearing rod 16, and the overlap block 25 is symmetrically distributed about the center of the limiting plate 9, a knocking rod 20 is slidingly arranged inside the overlap block 25, and an auxiliary plate 21 is fixedly connected to the end of the knocking rod 20, and a force-bearing plate 26 is fixedly connected to the surface of the knocking rod 20.

[0024] The end of the other side of the pressure rod 16 is fixedly connected to an auxiliary rod 19, and the auxiliary rod 19 is an inverted "L" structure when viewed from above, and the auxiliary rod 19 is initially in contact with the inner wall of the auxiliary plate 21. The surface of the force-bearing plate 26 is fixedly connected to a reset spring 27 that plays an elastic reset role, and the other side of the reset spring 27 is fixedly connected to the surface of the overlap block 25. The surface of the baffle 17 is fixedly connected to a second spring 18 that plays an elastic reset role, and the other side of the second spring 18 is fixedly connected to the surface of the overlap block 25.

[0025] Initially, the surface of the auxiliary rod 19 fits with the surface of the auxiliary plate 21. At this time, the auxiliary plate 21 is supported by the auxiliary rod 19. In the process of placing stones, when the staff adjusts the position of the extrusion plate 5 according to actual conditions, the right side of the extrusion plate 5 may contact the baffle 17. At this time, the baffle 17 moves in the direction of extruding the second spring 18. At the same time, when the baffle 17 moves, it will drive the pressure rod 16 and the auxiliary rod 19 to move synchronously. When the auxiliary rod 19 is not in contact with the auxiliary plate 21, the auxiliary plate 21 drives the knocking rod 20 to move inside the protective frame 22 under the action of the reset spring 27. Finally, the knocking rod 20 will hit the copper sheet 23 on the inner wall of the protective frame 22, causing the copper sheet 23 to make a sound, which is convenient for reminding the staff to follow this spacing. When stones are placed, the device will eventually be in an overweight state, which improves the overall safety of the device. The partition net 24 on the inner wall of the protection frame 22 prevents the copper sheet 23 from being hit by debris, thereby preventing false ringing and ensuring the accuracy of the sound alarm. When it is necessary to reset the auxiliary rod 19 and the auxiliary plate 21, the auxiliary plate 21 is pulled to return the auxiliary plate 21 to the initial position (at this time, the reset spring 27 is squeezed by the force plate 26 again), and then when the baffle 17 is not squeezed, the pressure-bearing rod 16 moves back under the action of the baffle 17 and the second spring 18, and then the pressure-bearing rod 16 drives the auxiliary rod 19 back to its original position. At this time, the auxiliary rod 19 will support the auxiliary plate 21 again, facilitating the next operation of the auxiliary plate 21 and the knocking rod 20.

[0026] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
