Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder transfer technology, specifically a hydraulic cylinder transfer device for a boom lift vehicle. Background Technology

[0002] The luffing cylinder is a key hydraulic actuator for the aerial work platform to achieve the luffing function of the boom. Simply put, the luffing cylinder pushes or pulls the boom of the aerial work platform by extending or retracting the piston rod, thereby changing the angle between the boom and the horizontal plane. This process is similar to the lever principle. The cylinder acts as a power source, adjusting the boom angle by changing the position of the point of action (the extension and retraction of the piston rod). However, due to its crucial role, the boom needs to be transferred during the production of the aerial work platform, thus requiring the use of a transfer device.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Currently, most luffing cylinders are haphazardly loaded onto simple transfer vehicles by hand and then transported to designated locations by these vehicles. This process easily causes collisions and scratches between the cylinders, resulting in surface defects in the products and failing to meet production requirements. Therefore, we have proposed a luffing cylinder transfer device for aerial work platforms to solve the aforementioned problems. Utility Model Content

[0024] 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.

[0025] Please see Figure 1 - Figure 3 This utility model provides a technical solution: a transfer device for a boom lift cylinder, including a moving part, the moving part including a base 1, four casters 11 and a handle 12, the four casters 11 being equidistantly installed at the bottom of the base 1, and the handle 12 being installed at the left end of the base 1.

[0026] The top of the base 1 is equipped with four support columns 2, four shock absorbers 3 and a buffer assembly. The top of the four shock absorbers 3 and the buffer assembly is fixedly connected to a bearing plate 4. The top of the bearing plate 4 is provided with multiple placement slots 5 at equal intervals.

[0027] Four support columns 2 are fixedly installed with connecting rods 6 between them. The top of two connecting rods 6 is fixedly installed with a first clamping plate 7, and the top of the two connecting rods 6 is slidably connected with a second clamping plate 8.

[0028] Two bolts 9 are installed at equal intervals on the inner side of the first clamping plate 7. At the same time, through holes 81 larger than two bolts 9 are opened at equal intervals on the inner wall of the second clamping plate 8. Meanwhile, multiple placement grooves 5 are opened at equal intervals on the inner walls of both the first clamping plate 7 and the second clamping plate 8, and arc-shaped grooves 10 are opened to match them.

[0029] The four support columns 2 and the buffer assembly can be installed through the base 1 in the movable component. Since the bearing plate 4 is installed on the top of the buffer assembly and multiple placement slots 5 are provided at equal intervals on the top of the bearing plate 4, one end of the luffing cylinder is inserted into the placement slot 5 through the first clamping plate 7 and pushed inward to make the two bolts 9 inserted into the two through holes 81. The first clamping plate 7 and the second clamping plate 8 are connected by nuts that are compatible with the two bolts 9 to fix the luffing cylinder. This avoids the luffing cylinder being randomly installed on the simple transport vehicle, which would cause collisions and scratches between the luffing cylinders.

[0030] Because the top of the bearing plate 4 is provided with multiple placement slots 5 at equal intervals, and the inner walls of the first clamping plate 7 and the second clamping plate 8 are provided with multiple placement slots 5 at equal intervals and are adapted to be provided with arc-shaped slots 10, this device can store multiple luffing cylinders at the same time. Furthermore, through the first clamping plate 7 and the second clamping plate 8, friction between multiple luffing cylinders during transportation can be avoided. At the same time, with the help of the buffer assembly and four shock absorbers 3, vibration and bumps can be reduced, thereby improving the stability during transportation.

[0031] See Figure 1 , Figure 3 The top of each of the two connecting rods 6 is provided with a convex groove 61, and the inner wall of each of the two convex grooves 61 is slidably connected with a convex block 16. The second clamping plate 8 is fixedly installed on the top of the two convex blocks 16. The multiple arc grooves 10 opened on the inner wall of the first clamping plate 7 are perpendicular to the multiple placement grooves 5. The inner wall of each of the multiple arc grooves 10 is equipped with an anti-slip pad 15.

[0032] Two convex blocks 16 can be installed through the convex grooves 61 opened at the top of the two connecting rods 6. Since the second clamping plate 8 is fixedly installed on the top of the two convex blocks 16, after one end of the luffing cylinder is inserted into the placement groove 5 through the first clamping plate 7, the second clamping plate 8 is pushed inward to drive the two convex blocks 16 to slide inward along the two convex grooves 61, so that the two bolts 9 can be inserted into the two through holes 81. At this time, the first clamping plate 7 and the second clamping plate 8 are connected by using nuts that are compatible with the two bolts 9, which can fix the luffing cylinder. At this time, the friction can be increased by multiple anti-slip pads 15, which can effectively fix the luffing cylinder and reduce the risk of accidents.

[0033] See Figure 1 , Figure 2 The buffer assembly includes a telescopic rod 101, two mounting plates 13, an upper hinge seat 102 and two lower hinge seats 103. The telescopic rod 101 and the two mounting plates 13 are all installed at the middle position of the top of the base 1. The two mounting plates 13 are symmetrically designed with the center of the telescopic rod 101. The top of each mounting plate 13 is provided with a guide groove, and a guide rod 14 is fixedly connected in each of the two guide grooves.

[0034] The upper hinge seat 102 is fixedly installed on the bottom of the support plate 4. The output end of the telescopic rod 101 is fixedly connected to the bottom of the upper hinge seat 102. The bottom of the two lower hinge seats 103 is equipped with limit sleeves 105. The two limit sleeves 105 are sleeved on the outer wall of the two guide rods 14. At the same time, there are two hinge rods 104 for the rotatable connection between the two lower hinge seats 103 and the upper hinge seat 102.

[0035] The upper hinge seat 102 in the buffer assembly can be installed through the bearing plate 4. Since the output end of the telescopic rod 101 is fixedly connected to the bottom of the upper hinge seat 102, the telescopic rod 101 is activated to push the upper hinge seat 102 to drive the bearing plate 4 to rise and fall. This allows the first clamping plate 7 and the second clamping plate 8 to fix the luffing cylinders at different heights. Since there are two hinge rods 104 rotating between the lower hinge seat 103 and the upper hinge seat 102, when the luffing cylinder is transported, when the bearing plate 4 is subjected to pressure, it drives the telescopic rod 101 to move downward. The two hinge rods 104 then push the two lower hinge seats 103 and drive the two limit sleeves 105 to slide on the outer wall of the guide rod 14. At this time, in conjunction with the shock absorber 3, the pressure on the bearing plate 4 is relieved, which can protect the luffing cylinder.

[0036] See Figure 1 , Figure 2 The inner sides of the four support columns 2 are provided with sliding grooves 21, and the outer wall of the bearing plate 4 is equidistantly equipped with sliders 41 of the same size as the four sliding grooves 21. The four sliders 41 are slidably connected in the four sliding grooves 21.

[0037] Four sliders 41 can be installed through the grooves 21 opened on the inner side of the four support columns 2. Since the four sliders 41 are installed at equal intervals on the outer wall of the bearing plate 4, when the luffing cylinder is transferred, the bearing plate 4 is subjected to pressure, which drives the telescopic rod 101 to move downward. The four sliders 41 are driven to slide down along the four grooves 21, which can improve the stability of the bearing plate 4.

[0038] During operation, the four support columns 2 and the buffer assembly can be installed by moving the base 1 in the component. Since the bearing plate 4 is installed on the top of the buffer assembly and the top of the bearing plate 4 is provided with multiple placement slots 5 at equal intervals, one end of the luffing cylinder is inserted into the placement slot 5 through the first clamping plate 7 and pushed inward to the second clamping plate 8 so that the two bolts 9 are inserted into the two through holes 81. The first clamping plate 7 and the second clamping plate 8 are connected by nuts that are compatible with the two bolts 9 to fix the luffing cylinder. This avoids the luffing cylinder being randomly installed on the simple transport vehicle, which would cause collisions and scratches between the luffing cylinders.

[0039] Because the top of the bearing plate 4 is provided with multiple placement slots 5 at equal intervals, and the inner walls of the first clamping plate 7 and the second clamping plate 8 are provided with multiple placement slots 5 at equal intervals and are adapted to be provided with arc-shaped slots 10, this device can store multiple luffing cylinders at the same time. Furthermore, through the first clamping plate 7 and the second clamping plate 8, friction between multiple luffing cylinders during transportation can be avoided. At the same time, with the help of the buffer assembly and four shock absorbers 3, vibration and bumps can be reduced, thereby improving the stability during transportation.

[0040] Two convex blocks 16 can be installed through the convex grooves 61 opened at the top of the two connecting rods 6. Since the second clamping plate 8 is fixedly installed on the top of the two convex blocks 16, after one end of the luffing cylinder is inserted into the placement groove 5 through the first clamping plate 7, the second clamping plate 8 is pushed inward to drive the two convex blocks 16 to slide inward along the two convex grooves 61, so that the two bolts 9 can be inserted into the two through holes 81. At this time, the first clamping plate 7 and the second clamping plate 8 are connected by using nuts that are compatible with the two bolts 9, which can fix the luffing cylinder. At this time, the friction can be increased by multiple anti-slip pads 15, which can effectively fix the luffing cylinder and reduce the risk of accidents.

[0041] The upper hinge seat 102 in the buffer assembly can be installed through the bearing plate 4. Since the output end of the telescopic rod 101 is fixedly connected to the bottom of the upper hinge seat 102, the telescopic rod 101 is activated to push the upper hinge seat 102 to drive the bearing plate 4 to rise and fall. This allows the first clamping plate 7 and the second clamping plate 8 to fix the luffing cylinders at different heights. Since there are two hinge rods 104 rotating between the lower hinge seat 103 and the upper hinge seat 102, when the luffing cylinder is transported, when the bearing plate 4 is subjected to pressure, it drives the telescopic rod 101 to move downward. The two hinge rods 104 then push the two lower hinge seats 103 and drive the two limit sleeves 105 to slide on the outer wall of the guide rod 14. At this time, in conjunction with the shock absorber 3, the pressure on the bearing plate 4 is relieved, which can protect the luffing cylinder.

[0042] Four sliders 41 can be installed through the grooves 21 opened on the inner side of the four support columns 2. Since the four sliders 41 are installed at equal intervals on the outer wall of the bearing plate 4, when the luffing cylinder is transferred, the bearing plate 4 is subjected to pressure, which drives the telescopic rod 101 to move downward. The four sliders 41 are driven to slide down along the four grooves 21, which can improve the stability of the bearing plate 4.

[0043] In summary, the device inserts one end of the luffing cylinder through the first clamping plate 7 into the placement groove 5, pushes the second clamping plate 8 inward so that the two bolts 9 are inserted into the two through holes 81, and uses nuts that are compatible with the two bolts 9 to connect the first clamping plate 7 and the second clamping plate 8 to fix the luffing cylinder.
