Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting equipment technology, and more specifically, to a fixed hoisting device connected to a pump base. Background Technology
[0002] A lifting device is a mechanical device used for hoisting operations. It typically consists of a general-purpose boom or a boom with a horizontal extension arm to facilitate lifting. Lifting devices are widely used on construction sites and other locations where heavy objects need to be hoisted.
[0003] Based on the above, the inventors have discovered that commonly used lifting devices for hoisting small equipment often have excessively large base dimensions due to safety anti-tipping design reasons. This limits their applicability to work environments with a radius greater than 1 meter around the small equipment body. However, many small pumps and motors in factories and production facilities are located in work environments with process pipelines, steel structures, and concrete steps within a radius of less than 1 meter. This makes commonly used lifting devices inconvenient to use, requiring multiple people to move pumps and motors up and down during disassembly and installation, resulting in high labor intensity for maintenance workers. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a fixed lifting device connected to the pump base, aiming to achieve a more practical purpose. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a fixed lifting device connected to the pump base. It can temporarily fix the base to the pump base anchor bolts using a fixing plate, and with the cooperation of the jacking screw and support components, ensure that the crane will not tip over. This enables the lifting of equipment such as pump bodies and rotors within a small range, ensuring work safety during the lifting process and reducing the labor intensity of maintenance workers. It also solves the problem that commonly used lifting devices for small equipment cannot be used in work sites where the surrounding environment of small pump equipment is less than 1 meter.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A fixed lifting device connected to a pump base includes a base and two anchor bolts fixed to the pump base. A support base is welded and fixed at the center of the top of the base. A crane is installed at the top of the support base. Set screws are provided at the four corners of the top of the base. The bottom ends of the set screws extend to the bottom of the base and are fixedly connected to support plates. Two fixing plates are fixedly connected to the end of the base near the pump base by fastening bolts and fastening nuts. The ends of the fixing plates away from the base are fixed to the corresponding anchor bolts by locking nuts. A support assembly is installed at the bottom of the other end of the base.
[0009] Furthermore, threaded sleeves are fixedly connected to the four top corners of the base, and the outer circumferential thread of the set screw is connected to the inside of the corresponding threaded sleeve.
[0010] Furthermore, an adjustment hole is provided at the top of one end of the base, and an adjustment hole is provided at the top of the fixing plate. The threaded part of the fastening bolt passes through the corresponding adjustment hole and adjustment hole in sequence, and is threadedly fixed with the fastening nut.
[0011] Furthermore, the anchor bolt passes through the corresponding adjustment hole and is threadedly fixed to the lock nut.
[0012] Furthermore, the support assembly includes two brackets fixed to the bottom of the base, a lever engaging between the two brackets, both ends of the lever extending outward and fixedly connected to a support rod, and the bottom end of the support rod rotatably connected to a support seat via a pin.
[0013] Furthermore, the card holder is provided with guide holes and multiple locking holes, and the guide holes are connected to the multiple locking holes.
[0014] Furthermore, the outer peripheries of both ends of the lever are engaged with the corresponding locking holes.
[0015] 3. Beneficial Effects
[0016] Compared with existing technologies, the advantages of this utility model are:
[0017] This solution, through the installation of a fixing plate, allows for temporary connection and fixation of the base to the anchor bolts on the pump base. With the cooperation of the jacking screws and support components, the base is supported from the bottom, ensuring that the crane will not tip over and improving the overall structural stability. This enables the pump body, rotor, and other equipment to be lifted within a small area, ensuring work safety during the lifting process and reducing the labor intensity of maintenance workers. It also solves the problem that commonly used lifting devices for small equipment cannot be used in work sites where the surrounding environment of small pump equipment is less than 1 meter.

The lifting requirements of the crane 4 are: lifting weight 200-1000KG, lifting height 1300-2200mm, and lifting range 1000-1700mm. A set screw 5 is provided at each of the four corners of the top of the base 1. The size of the set screw 5 is M30*210mm. The bottom end of the set screw 5 extends to the bottom of the base 1 and is fixedly connected to a support plate 6. Two fixing plates 9 with dimensions of 260mm*56mm are fixedly connected to the end of the base 1 near the pump base by fastening bolts 7 and fastening nuts 8. The end of the fixing plate 9 away from the base 1 is fixed to the corresponding anchor bolt 2 by locking nuts 10. A support assembly 11 is installed at the bottom of the other end of the base 1.
[0042] See Figure 2 Threaded sleeves 12 are fixedly connected to the four corners of the top of the base 1, and the outer circumferential thread of the set screw 5 is connected to the inside of the corresponding threaded sleeve 12.
[0043] See Figure 2 The base 1 has an adjustment hole 13 at one end of its top, and the fixing plate 9 has an adjustment hole 14 at its top. The threaded part of the fastening bolt 7 passes through the corresponding adjustment hole 13 and adjustment hole 14 in sequence, and is threadedly fixed to the fastening nut 8.
