A linkage-type static load counterweight unhooking device

Abstract

This utility model discloses a linkage-type static load counterweight unhooking device, characterized by comprising a hoisting platform, a roller frame, and a hook. By setting the hoisting platform to slide and connect the roller frame, and cooperating with the hoisting rope chain and the unlocking rope chain to control two movement states of the hoisting platform, the hoisting rope chain drives the lifting part of the hook to lift the static load counterweight, and the hook part hooks the static load counterweight for further lifting. Simultaneously, the unlocking rope chain pulls the unlocking part of the hook, causing the hook part to disengage from the static load counterweight. This achieves the hoisting and unlocking functions of the hoisting platform's lifting and unlocking actions on the static load counterweight. The purely mechanized drive method reduces material input and simplifies equipment operation. Furthermore, during the unlocking process, personnel do not need to stand on the stacked static load counterweights to guide and unlock the device, reducing manpower input and significantly lowering construction risks during the unlocking process.

Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment, and in particular to a linkage-type static load counterweight unhooking device. Background Technology

[0002] Static load test refers to the test method of applying vertical pressure, vertical uplift force or horizontal thrust to the top of the pile in stages, and observing the settlement, uplift displacement or horizontal displacement of the top of the pile over time, in order to determine the corresponding vertical compressive bearing capacity, vertical uplift bearing capacity or horizontal bearing capacity of a single pile.

[0003] Among them, the static load counterweights used to apply pressure during the test have a weight of several hundred kilograms to several tons, and several static load counterweights need to be stacked. Conventional structures use steel wire ropes to directly bind them, or use the lifting rings reserved on the static load counterweights, and rely on hooks to directly fix and unlock them.

[0004] However, directly using ropes or simple hooks for hoisting and unlocking operations presents the following problems: construction workers need to be on standby at three locations: the hoisting equipment, the stacking of static counterweights, and the testing of stacked static counterweights. This requires a large number of personnel, the fixing and unlocking steps are cumbersome, and the most dangerous stage during the transfer of static counterweights is the unlocking step when they are in place. Ropes and hooks are prone to breakage due to scratches and collisions, and collisions often occur during the alignment and stacking of static counterweights, posing a safety risk to the unlocking personnel located at the top of the stacked structure. Utility Model Content

[0005] Therefore, there is a need to provide a linkage-type static load counterweight unhooking device to solve the problems of the large number of personnel required for hanging and unlocking operations using ropes or simple hooks in the existing technology, the cumbersome fixing and unlocking steps, and the safety risks posed to the unlocking personnel located at the top of the stacked structure during the unlocking stage.

[0006] To achieve the above objectives, this utility model provides a linkage-type static load counterweight unhooking device, including a hoisting platform, a gravity block, a roller frame, a hook, a hoisting rope chain, and an unlocking rope chain;

[0007] The hoisting platform includes a platform body, hooks and a sliding rail. The hooks are connected to the upper part of the platform body and to the hoisting equipment. The sliding rail is set in the longitudinal direction, with one end connected to the platform body and the other end facing downwards from the platform body.

[0008] The gravity block is slidably connected to the sliding track of the hoisting platform, and the gravity block is connected to the hoisting equipment by a rope chain;

[0009] The roller frame is fixedly connected to the top of the hoisting platform, and there is a gap between the roller frame and the hoisting platform. A roller is connected to the lower shaft of the roller frame.

[0010] The hook is provided with a lifting part, a hooking part and an unlocking part. The lifting part is located at one end of the hook, the hooking part is located at the other end of the hook, and the unlocking part is located between the hooking part and the lifting part.

[0011] One end of the lifting rope chain is connected to the lifting platform, and the other end is connected to the lifting part of the hook;

[0012] One end of the unlocking rope is connected to the counterweight, and the other end of the unlocking rope passes upward through the upper part of the roller and then downward to connect with the unlocking part of the hook.

[0013] In a preferred embodiment of this application, the gravity block further includes a buffer spring, and the gravity block is connected to the lifting equipment via the buffer spring. By providing the buffer spring, the tension of the lifting equipment and the impact force during the descent of the platform body are buffered during the lifting or lowering process, preventing the impact force from directly damaging the ropes, chains, sliding rails, and sliding connection structures between the lifting equipment and the counterweight.

[0014] In a preferred embodiment of this application, the hoisting platform and roller frame are rectangular structures, and the number of hoisting rope chains, unlocking rope chains, hooks, and rollers is four. By setting the hoisting platform and roller frame to a rectangular structure, and the number of hoisting rope chains, unlocking rope chains, hooks, and rollers to four, it is easier to adapt to the static load counterweight of the rectangular structure, facilitate multi-point positioning, and avoid tilting of the static load counterweight.

[0015] In a preferred embodiment of this application, the lifting platform further includes adapter rollers, which are connected to the lower part of the sliding rail via a pivot. The adapter rollers facilitate guidance of the placement position when the lifting platform is placed on the static counterweight.

[0016] In a preferred embodiment of this application, the roller frame corresponds to two rollers for each unlocking rope chain, with the two rollers positioned on both sides above the sliding track. By positioning two rollers on both sides above each sliding track, interference and friction between the unlocking rope chain and the hoisting platform and roller frame are avoided when the unlocking rope chain passes through, ensuring the working stability and durability of the unlocking rope chain.

[0017] In a preferred embodiment of this application, the gravity block is slidably connected to the sliding track of the hoisting platform via pulleys. Using pulleys for this slidable connection reduces resistance during the gravity block's sliding process and facilitates the unlocking of the hook by the unlocking rope.

[0018] In a preferred embodiment of this application, the number of pulleys is two or more, and they are arranged along the height direction. By setting two or more pulleys arranged along the height direction, the problem of the gravity block getting stuck during the lowering process due to tilting is avoided, thereby improving the lifting efficiency of the gravity block and increasing the success rate of hook unlocking.

[0019] In a preferred embodiment of this application, the hoisting platform further includes a limiting rod, which is disposed at the lower part of the sliding rail and connected at both ends to adjacent sliding rails. By setting the longitudinally arranged limiting rod, the relative position of the lower part of the sliding rail is restricted, which helps to prevent the bottom of the sliding rail from directly contacting the ground or static load counterweight, and reduces the possibility of deformation after long-term use, thereby improving the service life and working stability of the sliding rail.

[0020] In a preferred embodiment of this application, the top of the platform body is a planar structure. By setting the top of the platform body to a planar structure, it is easier to hoist and install the equipment, and to avoid the ropes from getting tangled under the hoisting platform and the roller frame during the descent process.

[0021] In a preferred embodiment of this application, the pulley is a universal wheel structure. By setting the pulley to a universal wheel structure, it is easy to adapt to the relative movement position of the unlocking rope chain, facilitating multi-directional guidance.

[0022] Unlike existing technologies, the above technical solution has the following advantages: By setting a sliding rail on the hoisting platform to connect the counterweight, relying on the roller frame and the unlocking rope chain, and with the setting of the hoisting rope chain, two motion states of lifting and lowering of the counterweight are formed. With the lifting and lowering of both ends of the unlocking rope chain, the hoisting rope chain drives the lifting part of the hook to lift, the hook part hooks the static counterweight to lift, and the unlocking rope chain pulls the unlocking part of the hook, so that the hook part is disengaged from the static counterweight. This realizes the lifting and lowering action of the hoisting platform to lift and unlock the static counterweight. The purely mechanized drive method reduces material input, reduces the difficulty of using the equipment, and eliminates the need for personnel to stand on the stacked static counterweight to guide and unlock during the unlocking process, reducing manpower input and significantly reducing the construction risk during the unlocking process.

[0050] Please refer to the following: Figures 1 to 5 This utility model provides a linkage static load counterweight unhooking device, including a hoisting platform 10, a gravity block 60, a roller frame 20, a hook 30, a hoisting rope chain 40 and an unlocking rope chain 50;

[0051] The hoisting platform 10 includes a platform body 11, hooks 12, and sliding rails 15. The hooks 12 are connected to the upper part of the platform body 11. The hooks 12 can be lifting rings or hanging brackets to facilitate connection with the ropes, chains, or hooks 30 of the lifting equipment and to the lifting equipment. Specifically, the lifting equipment can be a vehicle-mounted crane or a tower crane. The sliding rails 15 are arranged in the longitudinal direction, with one end connected to the platform body 11 and the other end facing downwards from the platform body 11. In this embodiment, there are 4 sliding rails 15. In other embodiments, there can be any number of two or more.

[0052] The gravity block 60 is slidably connected to the sliding rail 15 of the hoisting platform 10. The gravity block 60 is connected to the hoisting equipment through a rope chain. The lifting and lowering of the hoisting equipment drives the gravity block 60 to slide on the sliding rail 15.

[0053] The roller frame 20 is fixedly connected to the upper part of the hoisting platform 10 by a bracket. There is a gap between the lower part of the roller frame 20 and the upper part of the hoisting platform 10. A roller 21 is connected to the lower part of the roller frame 20.

[0054] The hook 30 is provided with a lifting part 32, a hooking part 31 and an unlocking part 33. The lifting part 32 is provided at one end of the hook 30, the hooking part 31 is provided at the other end of the hook 30, and the unlocking part 33 is provided between the hooking part 31 and the lifting part 32.

[0055] One end of the lifting rope chain 40 is connected to the lifting platform 10, and the other end is connected to the lifting part 32 of the hook 30;

[0056] One end of the unlocking rope chain 50 is connected to the counterweight, and the other end of the unlocking rope chain 50 passes upward through the upper part of the roller 21 of the roller frame 20, and then downward to connect with the unlocking part 33 of the hook 30.

[0057] According to the above structure, during the operation of the linkage static load counterweight unhooking device, the operator located on the lifting equipment moves the linkage static load counterweight unhooking device as a whole to the area where the stacked static load counterweight blocks 70 are located, and performs the lifting operation. First, the platform body 11 is lowered, so that the sliding rail 15 or the preset bracket or baffle structure at the bottom of the platform body 11 contacts the static load counterweight block 70 first, so that the hook 30 approaches the preset hanging structure of the static load counterweight block 70. At this time, the hook 30, the lifting rope chain 40 and the unlocking rope chain 50 are all in a state of not bearing tension.

[0058] The operator located in the area where the static counterweight 70 is stacked and to be transferred manually hooks the hook 30 into the preset hanging structure of the static counterweight 70. Then, the operator of the lifting equipment pulls the hook 12 of the lifting platform 10 through the rope chain, which lifts the lifting platform 10 and the gravity block 60 through the rope chain. The gravity block 60 stops when it reaches the stop point on the sliding rail 15. The unlocking rope chain 50 does not exert additional tension on the hook 30. The lifting part 32 of the hook 30 is pulled by the lifting rope chain 40. The hook 31 allows the static counterweight 70 to be lifted and moved together with the linkage static counterweight unhooking device, keeping the lifting part 32 and the unlocking part 33 of the hook 30 in the vertical direction respectively. Upon reaching the designated stacking area for the static counterweight 70, and aligning it with the placement position of the static counterweight 70, the static counterweight 70 is first placed on the ground. Then, the lifting platform 10 of the linkage static counterweight release device contacts the static counterweight 70. When the sliding rail 15 or the pre-set bracket or baffle structure at the bottom of the platform body 11 contacts the static counterweight 70, the lifting rope chain 40 is already in a relaxed state and no longer exerts tension on the static counterweight 70. Subsequently, the lifting equipment continues to rapidly descend and release the rope connecting the lifting platform 10 and the gravity block 60. Under the action of gravity, the gravity block 60 descends rapidly along the sliding track 15. During the rapid descent of the gravity block 60, the unlocking rope chain 50 is tightened. After being guided by the rollers 21 of the roller frame 20, the unlocking rope chain 50 exerts a pulling force on the unlocking part 33 of the hook 30, causing the hook 30 to change angle and disengage from the preset hanging structure of the static load counterweight block 70, thus completing the unlocking step. Then, the linkage static load counterweight unhooking device is lifted again to reach the positions of the remaining static load counterweight blocks 70, and the lifting operation is repeated. By setting the sliding rail 15 of the hoisting platform 10 to slide and connect the counterweight, and relying on the roller frame 20 in conjunction with the unlocking rope chain 50 and the hoisting rope chain 40, two motion states of lifting and lowering of the gravity block 60 are formed. With the lifting and lowering of both ends of the unlocking rope chain 50, the hoisting rope chain 40 drives the lifting part 32 of the hook 30 to lift, the hook part 31 hooks the static load counterweight block 70 to lift, and the unlocking rope chain 50 pulls the unlocking part 33 of the hook 30, so that the hook part 31 disengages from the static load counterweight block 70. The hoisting platform 10 realizes the lifting and unlocking function of the static load counterweight block 70 by lifting and lowering. The purely mechanized drive method reduces material input, reduces the difficulty of using the equipment, and does not require personnel to stand on the stacked static load counterweight blocks 70 to guide and unlock during the unlocking process, reducing manpower input and significantly reducing the construction risk during the unlocking process.

[0059] Please refer to the following: Figures 1 to 5In a preferred embodiment of this application, the gravity block 60 further includes a buffer spring 13, and the gravity block 60 is connected to the lifting equipment via the buffer spring 13. By providing the buffer spring 13, the tension of the lifting equipment and the impact force on the rope chain between the lifting equipment and the gravity block 60 during the lifting or lowering process are buffered, preventing the impact force from directly damaging the rope chain between the lifting equipment and the counterweight, or the rope chain, sliding track 15 and sliding connection structure.

[0060] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the hoisting platform 10 and roller frame 20 are rectangular structures, and the number of hoisting rope chains 40, unlocking rope chains 50, hooks 30, and rollers 21 is four. By setting the hoisting platform 10 and roller frame 20 to a rectangular structure, and the number of hoisting rope chains 40, unlocking rope chains 50, hooks 30, and rollers 21 to four, it is easier to adapt to the static load counterweight of the rectangular structure, facilitate multi-point positioning, and avoid tilting of the static load counterweight. In some embodiments, the number of sliding rails 15 and gravity blocks 60 is also four, so that each hook 30 can be hoisted by an independent gravity block 60. In the accompanying drawings, only the two on the near side are shown from the side view perspective; the two on the far side are blocked and not shown.

[0061] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the hoisting platform 10 further includes an adapter roller 16, which is connected to the lower part of the sliding rail 15 via a rotating shaft. By providing the adapter roller 16, it is convenient to guide the placement position of the hoisting platform 10 when it is placed on the static counterweight block 70.

[0062] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the roller frame 20 has two rollers 21 corresponding to each unlocking rope chain 50, and the two rollers 21 are arranged on both sides above the sliding track 15. During use, each unlocking rope chain 50 passes through the two rollers 21 and is pulled by the hook 30 unlocking part 33 and the gravity block 60. By setting two rollers 21 on both sides above each sliding track 15, interference and friction between the unlocking rope chain 50 and the hoisting platform 10 and the roller frame 20 are avoided when passing through, ensuring the working stability and durability of the unlocking rope chain 50.

[0063] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the gravity block 60 is slidably connected to the sliding track 15 of the hoisting platform 10 via a pulley 61. Using the pulley 61 for this slidable connection reduces resistance during the sliding process of the gravity block 60, facilitating the unlocking of the hook 30 by the unlocking rope chain 50.

[0064] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the number of pulleys 61 is two or more, and they are arranged along the height direction. By setting two or more pulleys 61 arranged along the height direction, the problem of the gravity block 60 getting stuck in the lifting and lowering action due to tilting is avoided during the descent process, thereby improving the lifting and lowering efficiency of the gravity block 60 and increasing the success rate of unlocking the hook 30.

[0065] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the hoisting platform 10 further includes a limiting rod 14, which is disposed at the lower part of the sliding rail 15 and connected at both ends to adjacent sliding rails 15. By setting the longitudinally arranged limiting rod 14, the relative position of the lower part of the sliding rail 15 is restricted, which helps to prevent the bottom of the sliding rail 15 from directly contacting the ground or the static load counterweight 70, and reduces the possibility of deformation after long-term use, thereby improving the service life and working stability of the sliding rail 15.

[0066] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the top of the platform body 11 is a planar structure. By setting the top of the platform body 11 to a planar structure, it is easier to hoist and install the equipment, and to avoid the ropes from getting tangled under the hoisting platform 10 and the roller frame 20 during the descent process.

[0067] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the pulley 61 is a universal wheel structure. By setting the pulley 61 to a universal wheel structure, it is easy to adapt to the relative movement position of the unlocking rope chain 50, facilitating multi-directional guidance.

[0068] In some preferred embodiments, in order to avoid the hook 30 remaining on the preset hanging structure of the static counterweight 70 and to avoid repeated hooking, when the gravity block 60 is close to the bottom of the sliding track 15, the hook 30 can be pulled up by the unlocking rope chain 50 and jump up when it falls, causing it to shift and detach from the preset hanging structure of the static counterweight 70, and hang down on the upper surface of the static counterweight 70 together with the hoisting rope chain 40 and the unlocking rope chain 50.

[0069] In the above embodiment, in order to prevent the rope from failing to disengage, the guiding direction of the roller 21 can be offset from the moving direction of both ends of the hoisting rope chain 40, so as to achieve the lifting and disengagement effect of the unlocking rope chain 50.

[0070] In the above embodiments, the roller 21 may be provided with a positioning frame or opening to prevent the unlocking rope chain 50 from falling off.

[0071] In the above embodiments, the roller 21 can be selected as a pulley 61 structure with grooves.

[0072] In the above embodiments, the preset hanging structure of the static load counterweight 70 is formed by the steel bars or lifting rings pre-embedded in the static load counterweight 70 and the groove structure opened on the static load counterweight 70, so that the hook 30 can be hung in.

[0073] In the above embodiments, in order to enable the rope chain between the lifting equipment and the gravity block 60 to be connected and slide, the platform body 11 may be provided with an opening or a pulley 61 to accommodate the passage and sliding of the rope chain between the lifting equipment and the gravity block 60.

[0074] In the above embodiments, when there are four gravity blocks 60, multiple rope chains can be used to connect the gravity blocks 60 and the lifting equipment, or one rope chain can be used to connect two gravity blocks 60. This enables the pulling of the gravity blocks 60 and the lifting and unlocking of the hooks 30 when the linkage static load counterweight unhooking device is viewed from above as a rectangular or polygonal structure.

[0075] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
