Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to an auxiliary lifting device for installing a doorway-type bracket. Background Art

[0002] Portal supports refer to those used on urban bridges at higher heights, with greater load-bearing capacity, or with larger support spacing due to traffic needs. Hoisting refers to the installation and positioning of equipment using a crane or lifting mechanism. During inspection or maintenance, various lifting devices are used to lift equipment, workpieces, tools, and materials to change their position.

[0003] However, the existing processing equipment has the following deficiencies: when the existing equipment is used to hoist the doorway-type bracket, the staff uses a load-bearing rope to hang on two lifting rings, and then the staff starts the lifting equipment, so that the transition column can be gradually lowered. When the transition column is lowered, the first compression spring and the second compression spring can be gradually compressed. When the first compression spring and the second compression spring are gradually compressed, the second electrode block can be gradually lowered. Then, when the second electrode block is lowered, the second electrode block can be respectively contacted with multiple first electrode blocks, so that the alarm light emits different colors or sounds, which further facilitates the staff to grasp the weight of the heavy object. However, the existing device has the following problems: when the equipment is hoisted, the load-bearing rope is prone to sliding on the hook surface, causing friction between the load-bearing rope and the hook surface, resulting in damage to the load-bearing rope and a short service life.

By setting the reinforcement mechanism, it is convenient to reinforce the equipment connection, which can effectively reduce the instability caused by long-term stress on the equipment connection, thereby improving the overall stability of the equipment. In addition, the two sets of auxiliary mechanisms are symmetrically installed on the two opposite outer walls of the load-bearing plate 3, which is convenient for hoisting the auxiliary equipment and can effectively reduce the shaking of the door opening bracket during hoisting, thereby improving the overall safety of the equipment.

[0037] Furthermore, each set of protective mechanisms includes a placement block 5, a clamping block 6, two ear blocks 9, a fixing rod 10, two clamping rods 11, a limit block 12, a first spring 13, two second springs 14 and two push rods 15; wherein, the placement block 5 is in the shape of a rectangular parallelepiped and is parallel to the side wall of the bottom of the hook body 1, one side of which is fixedly mounted on one side wall of the bottom of the hook body 1, and a first semicircular limit groove 7 running through the top and bottom is provided in the middle of the other side; and one end of the clamping block 6 is hinged to one end of the other side of the placement block 5, and the other end is detachable It is clamped on the other end of the other side of the placement block 5, and a second semicircular limiting groove 8 running through the top and bottom is provided on the middle part of the side of the clamping block 6 close to the placement block 5; the first semicircular limiting groove 7 and the second semicircular limiting groove 8 together constitute a circular through hole for limiting and locking the carrying rope 2; the carrying rope 2 passes through the circular through hole and is connected to the load-bearing plate 3, and the carrying rope 2 can be limited and locked through the circular through hole to prevent it from shifting during lifting and use, thereby improving the overall stability and safety of the equipment. In addition, its two ear blocks 9 are fixedly installed at the top and bottom of one end of the other side of the placement block 5 in parallel and at intervals; the top and bottom ends of the fixing rod 10 are respectively fixedly connected between the two ear blocks 9; and a limit block 12 is fixedly installed on the other end of the other side of the placement block 5. The top and bottom ends of the outer wall of the limit block 12 are both spaced apart and have symmetrical U-shaped limit openings, with the opening directions of the two U-shaped limit openings facing each other. At the same time, one end of the clamping block 6 is hinged to the fixing rod 10, and the other end is detachably engaged in the corresponding U-shaped limit opening on the limit block 12. In addition, a first spring 13 is sleeved on the fixing rod 10, and its two ends are respectively fixedly connected to the ear block 9 and the clamping block 6 to reset the clamping block 6. The provision of the first spring 13 facilitates the control of the clamping block 6 in resetting, thereby improving the stability of the clamping block 6. At the same time, the clamping block 6 is provided with two L-shaped sliding holes 16 spaced apart in the height direction. The L-shaped sliding holes 16 extend from the other side of the clamping block 6 away from the placement block 5 to a side wall near the limit block 12. Each L-shaped sliding hole 16 is fixedly connected to a second spring 14. The provision of the second spring 14 facilitates the control of the clamping rod 11 to reset, while also improving the binding effect of the clamping rod 11 on the limit block 12. The clamping rod 11 has an L-shaped cross-section, and the short end of the clamping rod 11 can be slidably engaged in the L-shaped sliding hole 16 and fixedly connected to the second spring 14, while the long end can be slidably engaged in the corresponding U-shaped limit opening in the end of the limit block 12. In addition, one end of the push rod 15 is fixedly mounted on the end of the clamping rod 11, and the other end extends out of the other side of the clamping block 6. The push rod 15 is cylindrical in shape. The provision of the push rod 15 facilitates the control of the movement of the clamping rod 11, thereby improving the overall usability of the device.

[0038] By placing the carrying rope 2 in the placement block 5 and pushing the two push rods 15, the push rods 15 drive the clamping rod 11 to move, and the two second springs 14 are deformed under stress to generate elastic force. Then, the clamping block 6 is rotated, so that the first spring 13 is deformed under stress to generate elastic force. When the clamping block 6 cooperates with the placement block 5 to clamp the rope, the push rods 15 are released, so that the first spring 13 releases the elastic force, so that the clamping rod 11 is clamped in the U-shaped limit opening of the limit block 12, thereby limiting and locking the carrying rope 2. When the carrying rope 2 needs to be removed from the hook body 1, the two push rods 15 are pushed, and the push rods 15 drive the two clamping rods 11 to move in a direction close to each other, thereby moving the clamping block 6 out of the corresponding U-shaped limit opening in the end of the limit block 12. Then, the clamping block 6 is rotated, and the carrying rope 2 can be removed from the hook body 1. By cooperating the clamping rod 11 with the limiting block 12, the clamping block 6 can cooperate with the placing block 5 to clamp and position the carrying rope 2, thereby reducing the situation in which the carrying rope 2 slides on the hook body 1 of the hook during equipment lifting, causing wear and affecting the service life.

[0039] Furthermore, each set of reinforcement mechanisms includes a fixing ring 17 and a connecting ring 18; wherein, the fixing ring 17 is fixedly installed on the lower surface of the load-bearing plate 3, and an annular groove extending in the height direction is provided on the fixing ring 17, and the annular groove extends from the bottom surface of the fixing ring 17 to the middle part; at the same time, its connecting ring 18 is detachably clamped in the annular groove; in addition, the top of the lifting ring 4 is fixedly connected to the lower part of the connecting ring 18.

[0040] Specifically, sliding holes 19 are provided on the opposite sides of the fixing ring 17, and the sliding holes 19 pass through the outer wall of the fixing ring 17 to the inner wall and are connected to the annular groove; at the same time, connecting circular holes matching the sliding holes 19 are provided on the opposite sides of the connecting ring 18, and the connecting circular holes pass through the outer wall of the connecting ring 18 to the inner wall; and, an insertion rod 20 is slidably inserted into the sliding hole 19, one end of the insertion rod 20 is detachably engaged in the connecting circular hole, and the other end extends out of the sliding hole 19 and is fixedly connected to a pull block 21. By providing the insertion rod 20, the fixing ring 17 can cooperate with the connecting ring 18 to reinforce the connection between the lifting ring 4, thereby reducing the instability of the equipment connection caused by long-term stress; at the same time, the longitudinal section of the pull block 21 is a straight groove shape. By providing the pull block 21, it is easy to control the movement of the insertion rod 20, which is convenient for movement. In addition, a third spring 22 is provided on the insertion rod 20, and the two ends of the third spring 22 are fixedly connected to the fixing ring 17 and the pull block 21 respectively. By providing the third spring 22, it is convenient to control the insertion rod 20 and the pull block 21 to reset, and at the same time, the restraining effect of the insertion rod 20 is improved.

[0041] At the same time, each group of auxiliary mechanisms includes a fixed block 23, a hollow sleeve 24, an adjusting block 25, a cylinder 26 and a clamping block 27; wherein, one end of the fixed block 23 is fixedly connected to an outer side wall of the load-bearing plate 3, and the fixed block 23 is provided with a first rectangular hole 28 running through the top and bottom along the length direction; the hollow sleeve 24 is a rectangular cylindrical structure with a hollow interior, which is vertically arranged and the top is slidably connected to the first rectangular hole 28; the cylinder 26 is fixedly installed on the top surface of the fixed block 23, and the driving end is transmission-connected to the top of the hollow sleeve 24, for driving the hollow sleeve 24 to move in the first rectangular hole 28; the hollow sleeve 24 is sleeved on the adjusting block 25, and the adjusting block 25 is a rectangular parallelepiped structure, which is vertically arranged and movably and adjustably connected to the hollow sleeve 24; the bottom of the adjusting block 25 is fixedly connected to the clamping block 27, the cross-section of the clamping block 27 is L-shaped, and is arranged relative to the clamping block 27. The two cylinders 26 contract to move the two clamping blocks 27 toward or away from each other to clamp or release the door opening bracket. The clamping blocks 27 can clamp the door opening bracket, reducing the shaking of the door opening bracket during lifting and transportation, which affects safety.

[0042] It should be noted that a second rectangular hole 29 extending in the width direction is formed in the hollow sleeve 24, into which a T-shaped slider 30 is slidably connected. Furthermore, a U-shaped slot 31 extending in the height direction is formed in the adjustment block 25. One end of the T-shaped slider 30 passes through the second rectangular hole 29 and is movably and adjustably engaged in the U-shaped slot 31. The adjustment block 25 is fixed or loosened by adjusting the position of the T-shaped slider 30 in the U-shaped slot 31. Furthermore, a fourth spring 32 is fixedly connected in the second rectangular hole 29, one end of which is fixedly connected to the T-shaped slider 30. The provision of the fourth spring 32 facilitates the control of the reset of the T-shaped slider 30 and improves the restraining effect of the T-shaped slider 30.

[0043] The working principle of the auxiliary lifting device for doorway bracket installation is:

[0044] A protective mechanism is provided. When the device needs to be used, the carrying rope 2 is placed in the placement block 5, and the push rod 15 is pushed. The push rod 15 drives the clamping rod 11 to move. The second spring 14 is deformed by the force to generate elastic force. The clamping block 6 is rotated in the fixing rod 10. The first spring 13 is deformed by the force to generate elastic force. When the clamping block 6 cooperates with the placement block 5 to clamp the carrying rope 2, the push rod 15 is released. The first spring 13 releases the elastic force, causing the clamping rod 11 to engage with the inner wall of the limit block 12, and the device can be used. By providing a protective mechanism, it is convenient to protect the carrying rope 2 of the device, which can effectively reduce the wear and tear caused by the movement of the carrying rope 2 of the device with the hook surface during hoisting, reduce the short life of the carrying rope 2 in the device, and thus improve the overall practicality of the device.

[0045] By providing an auxiliary mechanism, when the equipment needs to be used, the T-shaped slider 30 is slid, and the fourth spring 32 is deformed under force to generate elastic force, causing the T-shaped slider 30 to lose its restraint on the U-shaped slot 31 on the surface of the adjustment block 25. The adjustment block 25 and the clamping block 27 are slid in the hollow sleeve 24. The T-shaped slider 30 is loosened, and the fourth spring 32 releases the elastic force, causing the T-shaped slider 30 to abut against the inner wall of the U-shaped slot 31. The cylinder 26 is retracted, and the cylinder 26 drives the hollow sleeve 24 and the clamping block 27 to move. When they move to a certain position, the two clamping blocks 27 clamp the hoisted door opening bracket, completing the use. By providing an auxiliary mechanism, the auxiliary equipment is facilitated for hoisting, which can effectively reduce the shaking of the door opening bracket during hoisting, reduce the unsafe situation of equipment hoisting, and thus improve the overall safety of the equipment.

[0046] By providing a reinforcement mechanism, when the device needs to be used, the pull block 21 is pulled, and the pull block 21 drives the insertion rod 20 to move. The third spring 22 is deformed under stress and generates elastic force, inserting the connecting ring 18 into the annular groove on the surface of the fixed ring 17. The pull block 21 is released, and the third spring 22 releases the elastic force, driving the insertion rod 20 and the pull block 21 to reset. The insertion rod 20 is inserted into the connecting circular hole on the surface of the connecting ring 18, and the device can be used. By providing a reinforcement mechanism, it is easy to reinforce the connection of the device, which can effectively reduce the instability caused by long-term stress on the connection of the device, reduce the possibility of the device falling off and affecting the lifting, and thus improve the overall stability of the device.

[0047] In summary, the auxiliary lifting device for installing a doorway bracket of the present application is convenient for protecting the equipment carrying rope 2 by providing a protective mechanism, which can effectively reduce the wear and tear caused by the movement of the equipment carrying rope 2 with the hook surface during lifting, and can also reduce the low life of the carrying rope 2 in the equipment, thereby improving the overall practicality of the equipment. At the same time, it is convenient for the auxiliary equipment to be lifted by providing an auxiliary mechanism, which can effectively reduce the shaking of the doorway bracket during lifting, and can also reduce the unsafe lifting of the equipment, thereby improving the overall safety of the equipment. In addition, it is convenient for reinforcing the equipment connection by providing a reinforcement mechanism, which can effectively reduce the instability caused by long-term stress on the equipment connection, and can also reduce the impact of lifting due to equipment falling off, thereby improving the overall stability of the equipment.
