DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling readers to have a thorough understanding of one or more aspects of the utility model, and these aspects of the utility model can be realized even without these specific details.

[0023] See also Figures 1 to 5 The utility model provides a simple hanging device, and the technical solution is as follows:

[0024] It includes a bearing wall 1, on which a horizontally placed working rod 2 is arranged. The working rod 2 is made of a galvanized square tube of 1.8 meters and 50×50*4mm. A sealing plate 3 is arranged at the tail end of the working rod 2. A diagonal brace 4 is arranged at the lower end of the bearing wall 1. The diagonal brace 4 is made of a galvanized square tube of 1.414 meters and 50×50*4mm. The other end of the diagonal brace 4 is connected to the bottom of the working rod 2, and the angle between the diagonal brace 4 and the working rod 2 is an acute angle of 45 degrees. When installing the working rod 2 and the diagonal brace 4, two 0.15*0.15m*8 thick steel bars are selected. The working rod 2 and the diagonal brace rod 4 are fixedly installed on the bearing wall 1 by using a plate and 8 M12 expansion bolts; a fixing ring 5 is provided on the end of the working rod 2 close to the sealing plate 3, and a connecting rod 6 is connected to the lower end of the fixing ring 5, and a fixed pulley 7 is provided at the lower end of the connecting rod 6. The fixed pulley 7 is selected to have a load-bearing capacity of 50KG, and a pull rope 8 is wound around the fixed pulley 7. The pull rope 8 is a Φ18 hemp rope. A splint 10 is provided on the end of the pull rope 8 away from the bearing wall 1, and four clamping blocks 11 are symmetrically provided on the left and right sides of the splint 10, and the pull rope 8 is connected to the splint 10 through a self-unloading component.

[0025] During the installation process, first cut a 45-degree angle at the two ends of a 1.414-meter-long galvanized square tube, and then weld the 45-degree angle galvanized square tube that has been cut at the end to the 1.8-meter-long galvanized square tube at a 1-meter position, with a welding angle of 45 degrees, thereby forming an equilateral triangle to enhance stability; 0.15*0.15 meter*8 thick steel plates are welded at both ends of the equilateral triangle to fix it to the wall; a 0.1-meter-long 50×50*4mm galvanized square tube is welded at the tail end of the working rod 2 as a sealing plate 3; and a fixed pulley 7 with a load capacity of 50KG is installed at the working rod 2 at a position 3200mm close to the sealing plate; after the entire device is welded, it is finally fixed to the load-bearing wall 1 where the object needs to be lifted by the two steel plates of the equilateral triangle and bolts. At this time, the installation of the simple lifting device is completed, and then the objects can be lifted by winding the pull rope 8 around the fixed pulley 7.

[0026] Before lifting the object, the clamping plate 10 is moved to the top of the object by operating the pull rope 8, and then the object is clamped by four clamping blocks 11, and then the pull rope 8 is pulled to lift the object, which improves convenience; at the same time, a self-unloading component is provided between the pull rope 8 and the clamping plate 10. After the object is moved to the designated position, the object can be quickly detached from the pull rope 8 through the self-unloading component, which improves convenience.

[0027] The self-unloading assembly includes a self-unloading box 9 connected to the pull rope 8, and the self-unloading box 9 is cylindrical, a groove 901 is provided in the self-unloading box 9, and the groove 901 is coaxially arranged with the self-unloading box 9, two card slots 902 are provided inside the self-unloading box 9, each card slot 902 is provided with a card block 903, and each card slot 902 is provided with a spring 904, and the two ends of each spring 904 are respectively connected to the card block 903 and the inner wall of the card slot 902, a fixing rod 12 is provided on the top of the clamping plate 10, a fixing block 13 is provided on the top of the fixing rod 12, and a separation block 14 is slidably provided on the fixing rod 12, and the fixing block 13 and the separation block 14 are both truncated cones with inclined circumferences, and the inclination direction of the fixing block 13 and the separation block 14 On the contrary; after the staff clamps the items with the four clamping blocks 11, they drive the self-unloading box 9 to the top of the fixed rod 12 by operating the pull rope 8, and slowly lower the self-unloading box 9 so that the fixed rod 12 enters the groove 901 of the self-unloading box 9. During the process, since the fixed block 13 is a truncated cone with an inclined body, it plays a guiding role. When the two clamping blocks 903 contact the fixed block 13, the spring 904 is squeezed and contracted, driving the clamping block 903 to retract. After passing the fixed block 13, the two clamping blocks 903 pop out and clamp with the lower end of the fixed block 13. The staff pulls the pull rope 8, and through the mutual restriction of the clamping block 903 and the fixed block 13, the items can be driven to move upward to the specified position through the clamping plate 10;

[0028] When the item reaches the designated position, the staff releases the pull rope 8 again, allowing the two blocks 903 to slowly fall down again. When passing the separation block 14, the two blocks 903 and the spring 904 are similarly squeezed by the extrusion force until they are close to the splint 10. Then the staff pulls the pull rope 8 again, and the two blocks 903 drive the separation block 14 to move upward until it is against the fixed block 13. The fixed block 13 and the separation block 14 are inclined in opposite directions. Under the guidance of the separation block 14, the two blocks 903 are squeezed out of the separation block 14 and the fixed block 13 in turn, so that the entire dump box 9 is separated from the fixed rod 12; through the cooperation between the dump box 9 and the fixed block 13 and the separation block 14, the staff only needs to control the pull rope 8 to loosen or tighten it, so that the dump box 9 and the fixed block 13 can be stuck or separated, thereby improving convenience.

[0029] Preferably, each slot 902 is a through slot, and each slot 902 is provided with a partition plate 15 at one end away from the groove 901, each partition plate 15 is provided with a connecting rod 905, each connecting rod 905 extends into the slot 902 and is connected to the block 903, and each partition plate 15 is connected to the dump box 9 by bolts, each spring 904 is wound around the corresponding connecting rod 905, and the two ends of each spring 904 are respectively connected to the block 903 and the partition plate 15, and each block 903 forms a separate design with the slot 902.

[0030] The connecting rod 905 connects the block 903 and the partition plate 15 into a whole, and the partition plate 15 is connected to the dump box 9 by bolts. When the block 903 is squeezed, since the connecting rod 905 extends outside the partition plate 15, it will extend outward when squeezed, and will not interfere with the normal operation trajectory of the block 903, thereby ensuring the stability of the block 903; and in the long-term use process, as the number of contacts between the block 903 and the fixed block 13 increases, it is easy to cause the block 903 to wear. At this time, the block 903, the connecting rod 905 and the partition plate 15 can be completely removed from the dump box 9 by bolts for inspection or replacement of spare parts, thereby ensuring the stable operation of the dump assembly and the stability of the lifting device.

[0031] The cross-section of each card block 903 is a right-angled trapezoid, and the extended length of each card block 903 is located at 1 / 2 of the fixed block 13; the inclined surface of the right-angled trapezoid has a certain guiding function, and cooperates with the fixed block 13 and the separation block 14 that are inclined frustum-shaped all around, so that the card block 903 can pass over the fixed block 13 and the separation block 14 more quickly, and conveniently clamp or disengage the dump box 9 from the fixed block 13, thereby improving convenience; limiting the extended length of the card block 903 to 1 / 2 of the fixed block 13 can ensure stability when transporting items to a certain extent. If it is too long, interference is likely to occur, and if it is too short, the card block 903 is likely to break, and the position of the fixed block 131 / 2 is a more reasonable position.

[0032] The diameter of the separation block 14 is larger than the diameter of the fixed block 13; if the diameter of the separation block 14 is smaller than or equal to the diameter of the fixed block 13, it is easy for the card block 903 to drive the separation block 14 to move upward and contact the fixed block 13, and the card block 903 is subjected to the upward pulling force and continues to move upward, while the card block 903 is contracted by the extrusion force. After the two card blocks 903 have completely passed through the separation block 14, the separation block 14 moves downward under the action of gravity. Since the diameter of the separation block 14 is smaller than or equal to the diameter of the fixed block 13, the two card blocks 903 may be stuck by the edge of the fixed block 13, resulting in the two card blocks 903 being unable to separate from the fixed block 13; then, the diameter of the separation block 14 is set to be larger than the diameter of the fixed block 13. When the two card blocks 903 separate from the separation block 14, it can be ensured that the two card blocks 903 can also separate from the fixed block 13, and will not interfere with the fixed block 13, thereby ensuring the stability of the dump box 9 when it is separated.

[0033] Preferably, the splint 10 is symmetrically provided with four slots 16 on the left and right sides, and each slot 16 is provided with a clamping block 11, each slot 16 is provided with a threaded groove 17, each threaded groove 17 is provided with a threaded rotary rod 18, and each threaded rotary rod 18 passes through the corresponding clamping block 11; when the staff fixes the object through the splint 10, the splint 10 is placed on the object, and the four threaded rotary rods 18 are rotated in turn, and the threaded rotary rods 18 drive the clamping block 11 to be tightened toward the slot 16, and the object is stably clamped by the four clamping blocks 11, and the thread is stable. When the threaded rotary rod 18 and the threaded groove 17 are threadedly tightened, the degree of clamping of the object is guaranteed to a certain extent; a through hole is provided on the clamping block 11, but no thread is provided in the through hole, so the splint 10 is subjected to the extrusion force of the threaded rotary rod 18 and follows the clamping of the object.

[0034] A plurality of rubber pads 19 are provided on one side of each clamping block 11 close to the clamping plate 10 ; the plurality of rubber pads 19 can increase the friction force of the clamping block 11 on the object, improve the degree of clamping of the object by the clamping block 11 , and improve the safety of the object.

[0035] A swivel joint 20 is provided between the pull rope 8 and the dump box 9; the swivel joint 20 can rotate 360 ​​degrees. When the object is moved to the corresponding position by the pull rope 8, the staff needs to adjust the direction of the object, and can rotate the object by manual control, which provides convenience.

[0036] A buffer pad 21 is provided at the connection between the fixing rod 12 and the splint 10; the separation block 14 will move upward under the drive of the two clamping blocks 903, and after the two clamping blocks 903 are separated from the separation block 14, the separation block 14 will move downward under the action of gravity, and then the separation block 14 will collide with the splint 10, which will cause damage to the separation block 14 in the long run. By providing a buffer pad 21 at the connection between the fixing rod 12 and the splint 10, a buffering effect can be played on the separation block 14, thereby avoiding damage to the separation block 14 and improving the service life of the separation block 14.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
