Description

Technical Field

[0001] This utility model relates to the technical field of gas station lifting devices, specifically a gas station lifting device with high safety. Background Technology

[0002] In the daily operation and equipment maintenance of gas stations, equipment hoisting operations are frequently required. Due to the need for hoisting large equipment, most of the hoisting equipment commonly used in gas stations currently has a relatively high height. In routine operations, such as when moving equipment, it is not necessary to move the equipment too high off the ground. During the hoisting process, the hook of the equipment is prone to swinging, which not only affects the stability of the operation, but also increases the safety risks of collision and falling in the special flammable and explosive environment of the gas station. If smaller hoisting equipment is used, it will not only fail to meet the needs of hoisting larger equipment, but also affect the passage of larger equipment.

[0003] Therefore, a highly safe gas station lifting device is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a highly safe gas station lifting device. Through the support column assembly and the top frame, coupled with the drive of the hydraulic rod, the height of the top frame can be flexibly adjusted. During normal operations, the support column assembly can be adjusted to its shortest length to reduce the height of the top frame, effectively reducing the swing amplitude of the hook, improving operational stability, and reducing the risk of collision and fall. When lifting large equipment, the top frame can be raised by the hydraulic rod to meet the requirements of higher lifting heights without the need for additional equipment replacement, thus avoiding waste of equipment resources and solving the problems mentioned in the background technology.

[0006] The support assembly includes a first support, a second support, and a positioning pin;

[0007] The first support column is fixedly connected to the upper surface of the base plate, and the second support column is fixedly connected to the lower surface of the top frame. The second support column is sleeved on the outside of the first support column. The first support column has multiple first pin holes on its opposite sides, and the second support column has second pin holes on its opposite sides. The positioning pin passes through the first pin holes and the second pin holes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example:

[0023] Please see Figure 1 - Figure 4 This embodiment provides a high-safety gas station lifting device, comprising a lifting beam 1, a top frame 2, and a base plate 3. The two ends of the lifting beam 1 are slidably connected to the two opposite sides of the inner side of the top frame 2. A support assembly 4 is connected to the bottom surface of the top frame 2. A hydraulic rod 5 is fixedly installed between the bottom surface of the top frame 2 and the upper surface of the base plate 3. The hydraulic rod 5 provides power for the lifting and lowering of the top frame 2. The support assembly 4 is used to support the top frame 2 and cooperate to achieve height adjustment. The support assembly 4 includes a first support 401, a second support 402, and a positioning pin 403. The first support 401 is fixedly connected to the upper surface of the base plate 3 to provide support for the entire device. The second support 402 is fixedly connected to the bottom surface of the top frame 2 and is sleeved on the outside of the first support 401. The height of the top frame 2 is changed by the relative sliding of the first support 401 and the second support 402.

[0024] Multiple No. 1 pin holes 6 are opened on the opposite sides of the No. 1 support column 401, and No. 2 pin holes 7 are opened on the opposite sides of the No. 2 support column 402. The positioning pin 403 passes through the No. 1 pin hole 6 and the No. 2 pin hole 7, and is used to fix the No. 1 support column 401 and the No. 2 support column 402 after the height is adjusted to ensure the stability of the structure.

[0025] Multiple mounting holes 8 are provided on the outer side of the first support column 401. A first guide wheel 9 is installed in the mounting holes 8 to guide the inner side of the second support column 402. A second guide wheel 10 is installed on the top of the first support column 401 to guide the other two inner sides of the second support column 402. The first guide wheel 9 and the second guide wheel 10 are used to guide the second support column 402 during the lifting and lowering process to ensure that the second support column 402 does not deviate during the lifting and lowering process and improve the stability of the adjustment process.

[0026] Four reinforcing ribs 11 are fixedly connected to the four corners of the inner side of the No. 1 support column 401. A reinforcing round tube 12 is fixedly connected between the two sides of the inner side of the No. 1 support column 401 near the No. 1 pin hole 6. The reinforcing round tube 12 structurally strengthens the No. 1 support column 401, while its inner side serves as the support surface for the positioning pin 403. The reinforcing ribs 11 further strengthen the round tube, enhancing the overall strength of the No. 1 support column 401 and enabling it to better withstand hoisting loads. Multiple reinforcing ribs 11 are fixedly connected to the sides near the mounting hole 8. A fixing plate 13 is fixedly installed, which is used to install the first guide wheel 9. The second support column 402 is fixedly connected to the outer side near the second pin hole 7. The outer side of the second pin hole 7 is fixedly connected to the second reinforcing rib 14. The inner side of the second support column 402 is coplanar with the inner side of the second pin hole 7. The inner side of the second support column 402 and the inner side of the second pin hole 7 jointly support the positioning pin 403, which improves the structural strength of the second support column 402 at the pin hole and prevents the second support column 402 from deforming when the positioning pin 403 is under force.

[0027] There are three No. 2 pin holes 7, and the number of No. 1 pin holes 6 is greater than the number of No. 2 pin holes 7, which gives the device multiple height adjustment positions to meet the height requirements of different hoisting scenarios. During routine hoisting, the three No. 2 pin holes 7 of the No. 2 support column 402 are aligned with the three No. 1 pin holes 6 at the bottom of the No. 1 support column 401 and are fixed with positioning pins 403. The spacing of the No. 2 pin holes 7 is equal to the spacing of the No. 1 pin holes 6 and is precision machined. At this time, the support column assembly 4 is in its shortest state and the top frame 2 is at its lowest point. Due to the lower height, the swing amplitude of the hook during hoisting is effectively reduced, the stability of the operation is improved, thereby reducing the risk of collision and fall and improving the safety during routine operations.

[0028] Three No. 1 support columns 401 are fixedly connected to one of the base plates 3. The two base plates 3 are symmetrically arranged, and a total of eighteen positioning pins 403 support the top. The arrangement of multiple sets of support columns and positioning pins 403 further enhances the load-bearing capacity and stability of the device. When the top structure and the load total 20 tons, considering that there may be uneven load in actual operation, the positioning pins 403 made of No. 45 steel are selected according to the safety factor of 2.5. When the diameter of the positioning pins 403 is greater than 35 mm, the force requirements can be met.

[0029] When hoisting larger equipment, the hydraulic rods 5 installed at the four corners of the top frame 2 are activated. The hydraulic rods 5 are telescopic sleeve type hydraulic rods 5, which are connected to external hydraulic equipment through pipes. When the multiple positioning pins 403 are no longer under force, the positioning pins 403 are pulled out, and then the hydraulic rods 5 are activated again. The hydraulic rods 5 drive the top frame 2 to rise, and the top frame 2 drives the second support column 402 to rise. After the top frame 2 rises to the preset height, the multiple positioning pins 403 are reinserted to connect the first support column 401 and the second support column 402. By using the driving force of the hydraulic rods 5 and the telescopic structure of the support column assembly 4, the height of the top frame 2 is increased, which meets the hoisting requirements of large equipment. There is no need to change the hoisting equipment, avoiding waste of equipment resources. At the same time, the first guide wheel 9 and the second guide wheel 10 play a guiding role during the lifting and lowering of the second support column 402, ensuring that the height adjustment process is smooth and stable. The first reinforcing rib 11, the reinforcing round tube 12, the second reinforcing rib 14, and the reinforcing plate 15 improve the overall strength and load-bearing capacity of the device.

[0030] The working principle of the above embodiment is as follows: the top frame 2 and the second support column 402 are raised and lowered by the extension and retraction of the hydraulic rod 5. The height is adjusted by the sleeve structure of the first support column 401 and the second support column 402. The positioning pin 403 passes through the first pin hole 6 and the second pin hole 7 to fix the adjusted height. The guide wheel ensures smooth lifting and strengthens the structural lifting device. In normal operation, the positioning pin 403 is inserted into the low pin hole to make the support column assembly 4 the shortest and the top frame 2 the lowest, reducing the swing of the hook. When hoisting large equipment, the positioning pin 403 is pulled out, the hydraulic rod 5 is started to raise the top frame 2, and the positioning pin 403 is inserted to fix it after it is in place.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
