Description

Technical Field

[0001] The utility model relates to the technical field of static load counterweight hoisting equipment, in particular to a frame positioning type static load counterweight hoisting equipment. Background Art

[0002] Static load test refers to a test method in which vertical pressure, vertical upward pull or horizontal thrust is applied step by step to the top of the pile, and the settlement, upward pull or horizontal displacement of the top of the pile is observed over time to determine the corresponding single pile vertical compressive bearing capacity, single pile vertical pull-out bearing capacity or single pile horizontal bearing capacity.

[0003] At present, the counterweight blocks of static load tests are hoisted by simple lifting equipment through wire tying or hook lifting. As described in Technical Solution 201310305451.1, only simple cranes are used for lifting operations, and the actual lifting operations are performed by on-site operators on their own. If special lifting equipment is used to adapt to the static load counterweight blocks with hanging components, so that the static load counterweight blocks are placed without the need for personnel, it will be difficult for the crane operator to position the lifting equipment, resulting in a long time for the lifting equipment to be docked, resulting in low docking efficiency. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a frame-positioning static load counterweight lifting device to solve the problem in the prior art that it is difficult for crane operators to position the lifting device, resulting in a long docking time and low docking efficiency for the lifting device.

[0005] The utility model provides a frame-positioning static load counterweight hoisting device, comprising a device body, a hanging assembly, a first guide assembly and a second guide assembly;

[0006] The equipment body is connected to the lifting equipment;

[0007] The hanging assembly is arranged on both sides of the equipment body, and is used to hang the static load counterweight block during lifting, or to unhook the static load counterweight block when the material reaches the placement position;

[0008] The first guide assembly is arranged on both sides of the equipment body and extends downwardly of the equipment body, and is used for positioning the static load counterweight in the height direction;

[0009] The second guide assembly is arranged in at least one direction in front of and behind the equipment body. The second guide assembly includes a transverse extension section and a longitudinal extension section. One end of the transverse extension section is connected to the equipment body, and the longitudinal extension section is connected to the transverse extension section, which is used for positioning in front of or behind the static load counterweight block.

[0010] Different from the prior art, the above technical solution has the following advantages: by setting a second guide assembly, which is located in at least one direction in front and rear of the equipment body, the top of the static load counterweight block is aligned through the transverse extension section, and the side of the static load counterweight block is aligned through the longitudinal extension section. Before the hanging assembly is hung, when the lifting equipment hangs the equipment body, the equipment body swinging on the rope is aligned in both directions, and cooperates with the first guide assembly to achieve the effect of guiding the hanging assembly to accurately align with the hooking area of ​​the static load counterweight block, thereby avoiding the danger of people being in the lifting and landing area of ​​the static load counterweight block and reducing the difficulty of lifting the static load counterweight block by the lifting equipment operator.

[0011] As a preferred embodiment of the present application, the hanging assembly includes a hanging hook and a hanging hook linkage. The hanging hook is connected to both sides of the equipment body through a rotating shaft, and includes a hook body and a counterweight. The hook body is located below the rotating shaft, and the counterweight is located above the rotating shaft. The counterweight is connected to the hanging hook linkage. The hanging hook linkage is used to drive the hanging hook to hang the static load counterweight using the hook body during lifting, or to unhook the hook body from the static load counterweight when the material falls to the ground. By setting the hanging hook and the hanging hook linkage, the hanging hook is rotated along the rotating shaft to achieve hooking and unhooking with the static load counterweight, and the hanging hook linkage is set to drive the hanging hook, so as to facilitate the driving process of the hanging hook.

[0012] As a preferred embodiment of the present application, the hook linkage member is a motor, and the telescopic end of the motor is connected to the counterweight part.

[0013] As a preferred embodiment of the present application, it further includes guide wheels, which are arranged on the first guide assembly on both sides of the device body, and the arc surfaces of the guide wheels on both sides of the device body are arranged opposite to each other. By arranging the guide wheels, it is convenient for the first guide assembly to guide in the height direction, and further accurately fix the hooking position.

[0014] As a preferred embodiment of the present application, there are two guide wheels on each side of the equipment body.

[0015] As a preferred embodiment of the present application, a height guide is further included, one end of which is connected to the second guide assembly, and the other end of which is extended to the bottom of the device body. By setting the height guide, after the second guide assembly is docked, the preset height guide can be relied on to make the second guide assembly contact the static load counterweight in the height direction, and then the relative position of the hanging assembly on the device body and the static load counterweight in the height direction can be accurately limited by the height guide, thereby improving the hooking efficiency of the hanging assembly.

[0016] As a preferred embodiment of the present application, the transverse extension section and the longitudinal extension section of the second guide assembly are connected by a lifting rod. By setting up a lifting rod to connect the transverse extension section and the longitudinal extension section, it is convenient to free up placement space for the side of the static load counterweight block during the placement process of the static load counterweight block, thereby avoiding the continuous placement of the longitudinal extension section causing the side space to be occupied during the placement process of the static load counterweight block.

[0017] As a preferred embodiment of the present application, the equipment body further comprises a hanging rack, the hanging rack is arranged on the upper part of the equipment body, and the equipment body is connected to the hanging device through the hanging rack. By arranging the hanging rack, it is convenient to contact the hanging rack after the annular segment rises, so that the lifting device drives the hanging rack and the equipment body connected to the hanging rack to be lifted together through the annular segment.

[0018] As a preferred embodiment of the present application, the length of the longitudinal extension section of the second guide assembly is greater than that of the first guide assembly. By setting the length of the longitudinal extension section of the second guide assembly to be greater than that of the first guide assembly, it is convenient to align the static load counterweight block through the longitudinal extension section before aligning the first guide assembly.
