Description

Technical Field

[0001] The utility model relates to the technical field of crane equipment, in particular to a cable-type lifting device for water conservancy project construction. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the people's needs for water resources in life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc.

[0003] In the prior art, since the construction span of water conservancy projects is large and the travel of ordinary cranes is insufficient, a cable-type lifting device is required to carry out the operation. However, after the lifting operation of the cable-type lifting device is completed, the cable may be stretched, causing the horizontal position of the lifting device to shift. If it is not corrected in time, it is easy to cause safety hazards and reduce the working efficiency of the device. Therefore, in order to solve the above problems, the utility model proposes a cable-type lifting device for water conservancy project construction. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a cable-type lifting device for water conservancy project construction. By setting up two sets of motors, the two winch drums can conveniently adjust the falling length of each cable, so that the lifter remains in a horizontal position, which is conducive to timely adjustment of the device after use, avoiding affecting subsequent use, reducing safety hazards, and maintaining stable working efficiency of the device.

[0005] The utility model provides the following technical solution: a cable-type lifting device for water conservancy project construction, comprising a movable frame, the bottom of the movable frame is fixedly installed with a connecting plate, the number of the connecting plates is symmetrically distributed front and back, and a lifting frame is fixedly installed between the two connecting plates, the middle of the lifting frame is provided with a cavity one and a cavity two, the number of the rotating shafts is movably sleeved in the cavity one and the cavity two and symmetrically distributed left and right, a winch drum is fixedly sleeved on the rotating shaft and located in the cavity one, and a motor is symmetrically fixedly installed in the cavity two, a gear one is fixedly sleeved on the output shaft of the motor, a gear two is meshed with the outer extension of the gear one, and the gear two is fixedly sleeved on the rotating shaft, and the motor drives the winch drum to rotate, so that the two winch drums adjust the falling length of their respective cable one, so as to avoid the inconsistent length of the cable one on both sides of the lifting frame after lifting the heavy object and affecting the subsequent use, thereby reducing safety hazards and maintaining the stability of the working efficiency of the device.

[0006] Preferably, the outer extension of the winch drum is engaged with cable 1, the bottom end of cable 1 is engaged with a lifter, a balancer is fixedly installed on the front of the lifter, and a hook is fixedly installed on the bottom of the lifter. The winch drum is driven to rotate by a motor, so that cable 1 on the winch drum is released, the lifter is lifted and lowered, and the hook is convenient for quickly lifting heavy objects.

[0007] Preferably, a driver is fixedly installed on the upper part of the movable frame. There are two drivers and they are symmetrically distributed on the left and right. The left and right parts of the driver are movably connected with driving wheels. The driving wheels are driven to rotate by the driver, so that the device can move flexibly, which is beneficial to improving the maneuverability of the device.

[0008] Preferably, the upper and lower parts of the inner cavity of the driver are respectively provided with cavity three, a connecting block is fixedly installed on the right part of the cavity three, a swing arm is movably connected to the connecting block through an axis, and a friction plate is fixedly installed on the end of the swing arm away from the connecting block, which contacts cable two through the friction plate to increase the friction between the device and cable two, so that the device is fixed and the stability of the device when lifting heavy objects is improved.

[0009] Preferably, a hydraulic rod is movably connected to the cavity three and located on the left side of the connecting block through an axis, and the telescopic end of the hydraulic rod is movably connected to the middle part of the swing arm through an axis, and a cable two is provided in the inner cavity of the driver, and the cable two is engaged with the outer extension of the driving wheel. The contact between the friction plate and the cable two is adjusted by the hydraulic rod to avoid the driving wheel slipping on the cable two due to excessive lifting weight, thereby effectively improving the reliability of the device and reducing the risk of the device tipping over.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The motor drives the capstan in cavity 1 to rotate, thereby releasing the cable 1 on the capstan, realizing the lifting of the lifter, and allowing the hook to lift the heavy object. After the device is lifted, the horizontal position of the lifter is detected by a balancer. When the horizontal position deviates, the motor drives the capstan to rotate, so that the two capstans adjust the falling length of their respective cable 1 respectively, so that the lifter returns to the horizontal position. This is conducive to timely adjustment of the device after use, avoiding the inconsistent length of cable 1 on both sides of the lifter after lifting the heavy object, affecting subsequent use, reducing safety hazards, and maintaining the stability of the device's working efficiency.

[0012] 2. The driver drives the driving wheel to rotate, so that the device moves along Cable 2. When it moves to the designated location, the hydraulic rod is started to extend the telescopic end of the hydraulic rod, thereby driving the swing arm to rotate, so that the upper and lower friction plates contact Cable 2 and clamp it, increasing the friction between the device and Cable 2, so that the device is fixed, which is beneficial to improve the stability of the device when lifting heavy objects, and avoid the driving wheel slipping on Cable 2 due to excessive lifting weight, effectively improving the reliability of the device, reducing the risk of the device tipping over, and providing protection for the personal safety of construction workers.
