Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to an auxiliary device for a cement hoisting machine used in construction engineering. Background Technology

[0002] In the field of modern construction engineering, cement is an indispensable basic material. When transporting cement vertically, hoists are needed. Hoists are large mechanical equipment that transports cement by changing potential energy, such as mine hoists and dam hoists. In a broader sense, elevators, overhead cranes, winches, jacks, cranes, gate hoists, etc. can all be called hoists. Hoists generally refer to large mechanical equipment with high power and strong lifting capacity.

[0003] Currently, Chinese utility model patent CN215160578U discloses a positioning auxiliary device for a lifting machine, including a base, a lifting mechanism, and a positioning mechanism.

A support rod is fixedly connected to the side wall of the bracket near the center of the base. This utility model includes a lifting mechanism that uses a screw to drive a moving block to move a lifting plate, ensuring stable movement of the lifting plate. A limiting rod and a slider are used to limit the movement of the moving block, further improving the stability of the movement of the moving block and the lifting plate. This utility model also includes a positioning mechanism that uses a second motor to make an infrared emitter emit infrared rays at a certain angle, facilitating adjustments to the base position by the operator and improving the efficiency of base adjustment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides an auxiliary device for a cement hoist in construction engineering, including a base 1, a lifting support 2, a lifting plate 3, and a counterweight box 4. The support is fixedly connected to the right side of the top of the base 1. The lifting plate 3 is movably connected to the inner wall of the lifting support 2. The counterweight box 4 is located on the left side of the top of the base 1. Adjustable sliding frames 5 are fixedly connected to both sides of the left side of the top of the base 1. Adjustable plates 6 are movably connected to the inner wall of the adjustable sliding frames 5. The left side of the adjustable plates 6 is fixedly connected to the right side of the counterweight box 4. A drive mechanism 7 is fixedly installed at the bottom of the counterweight box 4. A measuring component 8 is provided on the top of the outer side of the adjustable sliding frame 5. Auxiliary support components 9 are fixedly connected to both sides of the left side of the bottom of the counterweight box 4.

[0024] refer to Figure 1 and Figure 4 The drive mechanism 7 includes a connecting groove 71, which is located at the bottom of the counterweight box 4. A toothed plate 72 is fixedly installed on the inner wall of the connecting groove 71. A gear 73 is meshed with the top of the toothed plate 72. A drive motor 74 is fixedly installed on the top of the base 1. The gear 73 is fixedly connected to the output end of the drive motor 74.

[0025] As a technical optimization of this utility model, by setting a drive mechanism 7, the drive motor 74 can drive the gear 73 to rotate, and the counterweight box 4 can be moved laterally through the transmission of the gear 73 and the toothed plate 72. This allows the operator to quickly and accurately adjust the position of the counterweight box 4 according to actual needs, and realize flexible adjustment of the counterweight. Compared with the traditional fixed counterweight method, this significantly improves the device's ability to cope with lifting tasks of different weights.

[0026] refer to Figure 2 and Figure 3 The measuring component 8 includes a scale groove 81, which is located on the top of the outside of the adjusting slide frame 5. The scale groove 81 is arranged in several groups and is evenly distributed. The adjusting plate 6 is fixedly connected to both sides of the measuring pointer 82, which is located outside the scale groove 81.

[0027] As a technical optimization of this utility model, by setting the measuring component 8, the scale groove 81 can cooperate with the measuring pointer 82 to provide a visual position reference for the movement of the counterweight box 4. The operator can quickly adjust the counterweight box 4 to the corresponding scale according to the weight of the object being lifted, reduce manual adjustment errors, improve operating efficiency, and adapt to the counterweight adjustment needs under different working conditions.

[0028] refer to Figure 2 and Figure 4 The auxiliary support component 9 includes a threaded sleeve 91, which is fixedly connected to both sides on the bottom left side of the counterweight box 4. The inner wall of the threaded sleeve 91 is threadedly connected to a threaded support leg 92.

[0029] As a technical optimization of this utility model, by setting an auxiliary support component 9, the threaded leg 92 and the threaded sleeve 91 can be used together. The threaded leg 92 can be adjusted in height by rotation. After the counterweight box 4 is moved into place, it unfolds to support the device and distribute the weight of the device to the ground, thereby enhancing the overall stability and preventing tilting caused by the shift of the center of gravity.

[0030] refer to Figure 1 and Figure 4 A limiting plate 10 is fitted on the surface of the toothed plate 72. The limiting plate 10 is fixedly connected to the top of the base 1 and is U-shaped.

[0031] As a technical optimization of this utility model, by setting a limiting plate 10, the limiting plate 10 can be sleeved on the surface of the toothed plate 72, which plays a limiting and guiding role on the toothed plate 72, ensuring that the toothed plate 72 will not deviate or shake during the movement, thereby making the adjustment process of the counterweight box 4 smoother and more precise.

[0032] refer to Figure 1 and Figure 2 A control panel 11 is fixedly installed on the front side of the lifting bracket 2. The control panel 11 is electrically connected to the drive motor 74 through wires.

[0033] As a technical optimization of this utility model, by setting up a control panel 11, the operator can conveniently control the drive motor 74 from the front of the lifting bracket 2, realize remote operation of adjusting the position of the counterweight box 4, improve the convenience of operation and work efficiency, and at the same time allow the operator to more intuitively observe the overall status of the device when adjusting the counterweight.

[0034] refer to Figure 1 and Figure 4 The base 1 has sliding grooves 12 on both sides of the top, and the counterweight box 4 has mounting grooves 13 on both sides of the bottom. The front and rear sides of the inner wall of the mounting groove 13 are movably connected to the auxiliary wheel 14 through bearings. The bottom of the auxiliary wheel 14 is movably connected to the inner wall of the sliding groove 12.

[0035] As a technical optimization of this utility model, by setting the slide groove 12, the mounting groove 13 and the auxiliary wheel 14, the slide groove 12 and the auxiliary wheel 14 at the bottom of the counterweight box 4 can cooperate with each other, reducing the friction when the counterweight box 4 moves, making the counterweight box 4 easier and more flexible in the adjustment process, reducing the labor intensity of the operator, and also enhancing the stability of the counterweight box 4 in movement, avoiding jamming or deviation during movement.

[0036] The working principle and usage process of this utility model are as follows: In use, the base 1 is first moved to the desired cement lifting position. Based on the on-site construction environment and requirements, the threaded support leg 92 inside the threaded sleeve 91 is rotated to ensure the bottom of the threaded support leg 92 is in close contact with the ground, distributing the weight of the counterweight box 4 to the ground and enhancing overall stability. After determining the weight of the cement or other heavy object to be lifted, the operator starts the drive motor 74 via the control panel 11. The gear 73 at the output end of the drive motor 74 begins to rotate. Since the gear 73 meshes with the toothed plate 72, the toothed plate 72 drives the counterweight box 4 to move laterally along the adjusting slide frame 5. During the movement of the counterweight box 4, the adjusting plate 6 slides on the inner wall of the adjusting slide frame 5, providing guidance and stability to ensure smooth movement of the counterweight box 4. Simultaneously, the measuring pointers 82 on both sides of the adjusting plate 6 are in the scale grooves. The outer side of 81 moves synchronously, providing operators with a visual position reference. According to the weight of the object being lifted, the operator adjusts the counterweight box 4 to the appropriate scale position corresponding to the scale groove 81 to achieve a precise counterweight adjustment effect. This effectively prevents the center of gravity of the base 1 from shifting due to insufficient counterweight. After the counterweight box 4 is adjusted to the correct position, heavy objects such as cement are placed on the lifting plate 3, and the lifting function of the lifting bracket 2 is activated. The lifting plate 3 begins to vertically lift the heavy object from the inner wall of the lifting bracket 2. During the entire lifting process, since the position of the counterweight box 4 has been precisely adjusted according to the weight of the object, the reverse torque generated by the counterweight box 4 is balanced with the torque generated by lifting the object, effectively maintaining the stability of the center of gravity of the base 1 and preventing the device from tilting or tipping over. This greatly improves the stability and safety of the lifting process and can adapt to the counterweight adjustment needs under different working conditions.

[0037] In summary, this auxiliary device for a cement hoist in construction engineering, by setting up an adjusting slide frame 5, an adjusting plate 6, a drive mechanism 7, a measuring component 8, and an auxiliary support component 9, can adjust the position of the counterweight box 4 according to the weight of the object being lifted, thereby changing the counterweight effect. This effectively prevents the center of gravity of the base 1 from shifting due to insufficient counterweight, avoiding tilting or overturning of the device, and greatly improving the stability and safety of the lifting process. At the same time, the adjusting slide frame 5 and the adjusting plate 6 work together to make the adjustment process of the counterweight box 4 more stable and precise. This solves the problem that when the counterweight box is set with a fixed weight, the lack of a counterweight adjustment structure may result in insufficient fixed counterweight when lifting heavy objects, causing the center of gravity of the base to shift, leading to tilting or even overturning of the device, which seriously affects the stability and safety of the lifting process.
