[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] like Figures 1 to 5 As shown, the utility model provides a sling, including a hanging assembly 10 for connecting to a hoisting device; a support assembly 20, the hanging assembly 10 is connected to the support assembly 20, at least part of the hanging assembly 10 is located on the upper side of the support assembly 20; a first clamping assembly 30, mounted on the support assembly 20, the first clamping assembly 30 includes a first clamping part 310 and a first driving part 320, the first driving part 320 is threadedly engaged with the first clamping part 310, so as to drive the first clamping part 310 through the first driving part 320. The holding part 310 moves; the second clamping assembly 40, the second clamping assembly 40 includes a second clamping part 410 and a second driving part 420, the second driving part 420 is driven and connected to the second clamping part 410, so as to push the second clamping part 410 to move through the second driving part 420; wherein, the first clamping part 310 and the second clamping part 410 are arranged opposite to each other and are both located below the supporting assembly 20, so as to clamp the device to be installed by adjusting the position between the first clamping part 310 and the second clamping part 410.

[0033] It can be seen that the present invention is provided with a hanging assembly 10, a support assembly 20, a first clamping assembly 30 and a second clamping assembly 40. By adjusting the distance between the first clamping component 310 and the second clamping component 410, the present invention can adapt to various sizes and shapes of devices to be installed, can meet the lifting requirements of different equipment, and broaden the application range of the sling; the relative movement between the first clamping component 310 and the second clamping component 410 can accurately control the position of the device to be installed, ensure its stability and accuracy during the lifting process, and the first driving component 320 and the first clamping component 310 are set to be threaded, and the second driving component 420 and the second clamping component 410 are driven and connected, which can achieve fast and accurate clamping and releasing operations. Workers only need to simply control the driving components to complete the clamping and lifting of the device to be installed, which greatly improves work efficiency, reduces labor intensity, and significantly reduces safety risks during the lifting process, effectively avoids personal injury and collision between the fuel pump and surrounding components, and solves the problem of low efficiency in the installation and disassembly process of the fuel pump in the prior art.

[0034] Optionally, the utility model can be applied to a fuel pump.

[0035] like Figure 2 and Figure 3 As shown, the first driving component 320 includes a driving screw, which is rotatably arranged and extends along the distribution direction of the first clamping component 310 and the second clamping component 410; the first clamping assembly 30 includes a first clamping plate 340 and a transmission component 350 that are interconnected, and the transmission component 350 is threadedly engaged with the driving screw to drive the transmission component 350 to move along the driving screw when the driving screw rotates, thereby driving the first clamping plate 340 to move.

[0036] Through the cooperation of the drive screw and the transmission component 350, the utility model can achieve precise movement of the first clamping plate 340 along the drive screw, ensuring stable clamping of the fuel pump during the lifting process. This precise adjustment mechanism reduces the relative movement between the fuel pump and the clamp, avoiding possible damage during the lifting process.

[0037] Optionally, the transmission component 350 includes a transmission nut, which is fixedly connected to the first clamping plate 340 and adapted to the driving screw. By cooperating with the transmission nut and the driving screw and utilizing the high-precision transmission characteristics of the screw, the moving distance of the first clamping plate 340 can be accurately controlled, thereby achieving precise clamping of the fuel pump and avoiding damage to the fuel pump or installation deviation caused by inaccurate clamping.

[0038] like Figure 3As shown, there are two drive nuts, one located on opposite sides of the first clamping plate 340. The provision of two drive nuts allows the first clamping plate 340 to receive equal thrust on both sides of the drive screw, ensuring symmetry during the clamping process of the fuel pump, thereby maintaining better balance during the lifting process.

[0039] Specifically, the first driving component 320 further includes a mounting sleeve 321 and a mounting block 322 . The driving screw is rotatably mounted in the mounting sleeve 321 . The mounting block 322 is disposed on the supporting assembly 20 . The driving screw is rotatably mounted in the mounting block 322 .

[0040] like Figure 2 As shown, the driving screw is located above the support assembly 20, and an avoidance groove 50 is provided on the support assembly 20, which extends along the extension direction of the driving screw. The first clamping plate 340 includes a first main plate body 341 and a first connecting plate body 342 that are connected to each other. The first connecting plate body 342 passes through the avoidance groove 50, and the transmission component 350 is connected to the plate body of the first connecting plate body 342 located above the support assembly 20.

[0041] like Figure 3 As shown, the sling further includes two first guide fixing blocks 60 , which are both arranged on the support assembly 20 and respectively arranged on both sides of the first connecting plate body 342 to guide the moving direction of the first connecting plate body 342 .

[0042] The two first guide fixing blocks 60 are symmetrically distributed on the support assembly 20, and are respectively located on both sides of the first connecting plate body 342. They can accurately guide the moving direction of the first connecting plate body 342, ensuring that during the lifting process, the first connecting plate body 342 can move smoothly along the preset trajectory, avoiding collisions between the fuel pump and the lifting equipment components that may be caused by deviation of the moving path.

[0043] like Figure 4 and Figure 5 As shown, the second driving component 420 includes a piston cylinder 430 and a connecting head 440 . The cylinder body of the piston cylinder 430 is installed on the supporting assembly 20 . The piston rod 460 of the piston cylinder 430 is connected to the connecting head 440 . The connecting head 440 is connected to the second clamping component 410 .

[0044] Optionally, the connecting head 440 is a floating head, which includes a fixed connecting member and a floating connecting member. The fixed connecting member is connected to the second clamping component 410 , and the floating connecting member is connected to the piston rod 460 .

[0045] Connector 440 is designed as a floating connector, further enhancing the flexibility and safety of the hoist during operation. The floating connector consists of a fixed connector and a floating connector. The fixed connector provides a stable connection to the second clamping member 410, ensuring structural strength and accurate positioning. The floating connector, connected to piston rod 460, allows for fine-tuning during the lifting process based on changes in the fuel pump or the surrounding environment. This effectively absorbs and compensates for lateral and longitudinal forces caused by lifting operations, fuel pump size differences, or incomplete installation alignment, preventing unnecessary stress or damage to the fuel pump.

[0046] like Figure 4 As shown, the second clamping component 410 includes a second main plate body 411 and a second connecting plate body 412 connected to each other, and the sling also includes two second guide fixing blocks 70. The two second guide fixing blocks 70 are both arranged on the support assembly 20 and respectively arranged on both sides of the second connecting plate body 412 to guide the moving direction of the second connecting plate body 412.

[0047] By setting the first guide fixing block 60 and the second guide fixing block 70 on the support assembly 20, the movement direction of the first connecting plate body 342 and the second connecting plate body 412 can be effectively guided, ensuring the stable fit of each component during the lifting process, thereby improving the overall stability and safety.

[0048] Specifically, the first clamping component 310 includes a first clamping plate 340, which is L-shaped; and / or the second clamping component 410 includes a second clamping plate 450, which is L-shaped; and / or the hanging assembly 10 includes a hanging ring 110 and a hanging rope 120 passed through the hanging ring 110, and the support assembly 20 includes a support plate body 210 and two bent plate bodies 220 arranged on the support plate body 210, and the two bent plate bodies 220 are both fixed on the upper side of the support plate body 210, and the two ends of the hanging rope 120 are respectively connected to the two bent plate bodies 220.

[0049] Specifically, the combined use of first drive component 320 and second drive component 420 enables the fuel pump to be stably clamped on both sides. The first clamping plate 340 moves under the action of the drive screw, while the second clamping plate 450 is pushed by the piston cylinder 430. This double-sided clamping design improves balance and safety during the lifting process.

[0050] The L-shaped design of the first clamping plate 340 and the second clamping plate 450 can better fit the shape of the fuel pump, provide a more stable clamping force, and at the same time reduce the pressure on the surface of the fuel pump, avoiding scratches or damage that may occur during the clamping process.

[0051] Preferably, the lifting ring 110 is made of high-strength alloy material with excellent load-bearing capacity and wear resistance, ensuring that it can bear the weight of the fuel pump without deformation or breakage during the lifting process, and the surface is anti-slip treated to facilitate workers to stably control the lifting device.

[0052] The lifting rope 120 is preferably made of high-strength, low-elasticity steel wire rope, which has excellent load-bearing capacity and fatigue resistance. Its outer layer is coated with a wear-resistant and corrosion-resistant protective layer, which increases its service life and ensures operational safety. Bent plates 220 are provided at both ends of the lifting rope 120 to ensure a secure connection with the lifting ring 110 and the support plate 210.

[0053] Preferably, the bent plate body 220 is made of thick steel plate with good rigidity and stability. It is designed with a reasonable reinforcing rib structure to disperse the stress during the lifting process and reduce deformation. The surface is sandblasted and anti-rust coated to improve the corrosion resistance and aesthetics.

[0054] Preferably, the support plate 210 is made of high-strength aluminum alloy, which not only ensures sufficient load-bearing capacity but also reduces the overall weight. It can effectively disperse the load of the sling and maintain balance and stability during the lifting process. The surface of the support plate 210 is specially treated to enhance the friction with the lifting rope 120 to prevent slipping.

[0055] Preferably, the first clamping plate 340 and the second clamping plate 450 are made of a wear-resistant and corrosion-resistant alloy material, and the surface is covered with a soft rubber pad to reduce friction and damage to the surface of the clamping device. A reasonable clamping angle and clamping force adjustment mechanism are designed to ensure that the left side of the fuel pump can be firmly clamped.

[0056] Preferably, the second driving component 420 uses a high-precision, low-noise pneumatic element with the characteristics of fast response and stable force. Its stroke is adjustable and can be precisely controlled according to the size and shape of the clamping device to ensure that the second clamping component 410 can fit tightly and fix the left side of the device to be clamped, and a protective cover is provided on the outside of the second driving component 420 to prevent dust and impurities from entering.

[0057] Preferably, the drive screw is a high-precision ball screw, which features high transmission efficiency and precise positioning. Its surface is rust-proofed and internally lubricated with high-quality grease, reducing operational resistance and wear. A handwheel or electric drive device is provided at one end of the drive screw, allowing workers to flexibly control the tightening and loosening of the right clamping plate.

[0058] Preferably, the first guide fixing block 60 and the second guide fixing block 70 are made of high-strength cast iron material, and are provided with precise slideways and guide mechanisms inside, ensuring that the first clamping component 310 can move smoothly along a predetermined trajectory under the drive of the first driving component 320, thereby achieving precise clamping of the right side of the clamping device.

[0059] In specific implementation, the working process of the sling of the utility model when lifting the fuel pump is as follows:

[0060] Initial state: The sling is inactive. The spacing between the first clamping assembly 30 and the second clamping assembly 40 is large enough to accommodate fuel pumps of varying sizes. The drive screw of the first drive component 320 is in its initial position, and the first clamping component 310 is not clamping the fuel pump. The piston cylinder 430 of the second drive component 420 is inactive, and the second clamping component 410 is not pressing against the fuel pump.

[0061] Approaching the fuel pump: A worker controls a crane or trolley to move the sling with the lifting ring 110 to the top of the fuel pump. The lifting rope 120 is connected to the support plate 210 through the bent plate 220 to ensure the overall stability of the sling.

[0062] Initial positioning of the first clamping member 310: When the sling approaches the fuel pump, the worker ensures through vision or auxiliary tools that the first clamping plate 340 can initially support the right side of the fuel pump.

[0063] The first clamping component 310 is clamped: the worker rotates the driving screw, and through the transmission action of the driving screw, the first clamping component 310 is driven to move along the direction of the first guide fixing block 60, gradually approaching and clamping the right side of the fuel pump. Among them, the adjustment process of the driving screw can be precisely controlled according to the specific size of the fuel pump to ensure that the clamping force is moderate and stable.

[0064] The second clamping component 410 is tightened: After the first clamping plate 340 is clamped, the worker starts the piston cylinder 430. The piston rod 460 of the piston cylinder 430 extends and presses the second clamping plate 450. Under the push of the piston cylinder 430, the second clamping plate 450 gradually approaches and fits tightly against the left side of the fuel pump, thereby achieving double-sided clamping of the fuel pump.

[0065] Hoisting the fuel pump: After the first clamping plate 340 and the second clamping plate 450 firmly clamp the fuel pump, the worker controls the crane or trolley to lift the sling together with the fuel pump. During the lifting process, the various components of the sling are kept in close coordination to ensure the stability and safety of the fuel pump during movement.

[0066] Installation or removal: After the fuel pump is hoisted to the designated location, workers can perform installation or removal operations as needed. Once the operation is completed, the screw and piston cylinder 430 are driven in reverse, causing the first clamping plate 340 and the second clamping plate 450 to release the fuel pump, and the hoist is returned to its original position.

[0067] Compared with the prior art, the beneficial effects of the present invention are:

[0068] Ease of use and improved efficiency: This new design simplifies and expedited the entire hoisting process by optimizing its structural design, such as using a driver to adjust the distance between the first clamping plate 340 and the fuel pump, and using a design that forces the piston cylinder 430 to press against the second clamping plate 450. Workers can quickly secure and hoist the fuel pump with simple operations, significantly improving operational efficiency and reducing the tedious and time-consuming manual handling.

[0069] Improved Safety: Traditional manual handling or simple tool-assisted lifting methods pose significant safety risks, such as personal injury and collisions between the fuel pump and surrounding components. This new lifting system effectively avoids these issues through precise clamping and a stable lifting mechanism. Furthermore, all lifting components are constructed from high-strength, wear-resistant, and corrosion-resistant materials, enhancing overall safety and reliability.

[0070] Reduced labor intensity and improved working environment: Because this spreader enables rapid and stable lifting of fuel pumps, workers no longer need to perform heavy manual handling, significantly reducing labor intensity. Furthermore, the spreader's automated and mechanized operation improves the working environment, increasing efficiency and comfort.

[0071] Improved assembly quality: Traditional manual hoisting methods often make it difficult to ensure precise alignment and fixation of the fuel pump with surrounding components, which can easily affect the overall assembly quality of the engine. However, this utility model, through precise clamping and adjustment mechanisms, can ensure the stability and accuracy of the fuel pump during the hoisting process, thereby improving assembly quality and overall engine performance.

[0072] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0073] like Figures 1 to 5As shown, a sling of the present invention includes a hanging assembly 10 for connecting to a hoisting device; a support assembly 20, the hanging assembly 10 is connected to the support assembly 20, at least part of the hanging assembly 10 is located on the upper side of the support assembly 20; a first clamping assembly 30, mounted on the support assembly 20, the first clamping assembly 30 includes a first clamping part 310 and a first driving part 320, the first driving part 320 is threadedly engaged with the first clamping part 310, so as to drive the first clamping part 310 through the first driving part 320.

[0074] It can be seen that the present invention is provided with a hanging assembly 10, a support assembly 20, a first clamping assembly 30 and a second clamping assembly 40. By adjusting the distance between the first clamping component 310 and the second clamping component 410, the present invention can adapt to various sizes and shapes of devices to be installed, can meet the lifting requirements of different equipment, and broaden the application range of the sling; the relative movement between the first clamping component 310 and the second clamping component 410 can accurately control the position of the device to be installed, ensure its stability and accuracy during the lifting process, and the first driving component 320 and the first clamping component 310 are set to be threaded, and the second driving component 420 and the second clamping component 410 are driven and connected, which can achieve fast and accurate clamping and releasing operations.
