Description

Technical Field

[0001] This utility model relates to the field of equipment moving devices, and in particular to a welding machine moving trolley. Background Technology

[0002] In the fields of industrial manufacturing and maintenance, welding operations often require frequent relocation of welding equipment depending on changes in the work site. Traditionally, welding machines are mostly stationary, and when the work location changes, they often need to be moved manually or placed on a trolley with wheels.

[0003] However, the presence of wheels on the bottom of the trolley creates a height difference between the platform and the ground, necessitating manual lifting of the welding machine to the required height during loading, unloading, or positioning. This increases operational difficulty and labor intensity, while also reducing work efficiency. Furthermore, improper operation during lifting and movement can lead to safety hazards such as equipment slippage or tipping, affecting operational safety. Therefore, this paper proposes a mobile equipment trolley to address these issues. Utility Model Content

[0004] The main purpose of this utility model is to provide a mobile equipment trolley to solve the problem that existing welding machine handling devices still have significant shortcomings in terms of ease of use and safety.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a mobile equipment trolley, including two symmetrically arranged support base plates, each with a pulley at one of the four corners of the bottom and a support rod at one of the four corners of the top, and a top box at the top of the support rods. A lifting platform is movably arranged between the two support base plates, and connecting frames are symmetrically arranged on both sides of the top of the lifting platform. Two sliding sleeves are arranged on the outer side of the connecting frames, and the two sliding sleeves are respectively slidably fitted onto the two corresponding support rods. A rotatable lifting screw is also arranged between the two support base plates and the top box. A lifting threaded sleeve is threaded onto the outer side of the connecting frame and fitted onto the corresponding lifting screw. A drive mechanism that simultaneously drives the two lifting screws to rotate is arranged at the bottom of the top box.

[0006] In a preferred embodiment, the drive mechanism includes turbines respectively disposed above and outside the two lifting screws, two bearing seats symmetrically disposed at the bottom of the top box, a drive shaft rotatably disposed between the two bearing seats, and worm gears connected to the turbines passing through the bearing seats at both ends of the drive shaft. A first drive device is also disposed at the bottom of the top box, and the first drive device is used to dispose of a transmission component between the drive shafts.

[0007] In the preferred embodiment, the top of the lifting platform is equipped with a divider.

[0008] In the preferred embodiment, the divider is movably mounted on the lifting platform, and an adjustment mechanism for controlling the movement of the divider is provided between the two connecting frames.

[0009] In the preferred embodiment, two transverse sliding grooves are symmetrically arranged on the lifting and placing platform, and transverse sliding rods are installed in the transverse sliding grooves. The two ends of the bottom of the divider are respectively slidably fitted onto the two transverse sliding rods.

[0010] In a preferred embodiment, the adjusting mechanism includes a transverse lead screw rotatably disposed between two connecting frames, a second drive device connected to the transverse lead screw is disposed on the outer side of one of the connecting frames, and a transverse internal thread shaft that is threadedly engaged with the transverse lead screw is disposed on the top of the partition.

[0011] In the preferred embodiment, the top of the lifting platform is also equipped with a gas cylinder storage rack and a battery located behind the partition.

[0024] Example 1

[0025] like Figure 1-5 As shown, a mobile equipment trolley includes two symmetrically arranged support base plates 1. Each support base plate 1 has four casters 2 at its bottom corners and four support rods 3 at its top corners. In this embodiment, the support rods 3 are cylindrical, and a top box 4 is provided at the top of each support rod 3, thus forming a gap between the two support base plates 1. A lifting platform 5 is movably arranged in the gap between the two support base plates 1. Connecting frames 6 are symmetrically arranged on both sides of the top of the lifting platform 5. Two sliding sleeves 7 are provided on the outer side of the connecting frames 6. The two sliding sleeves 7 are respectively slidably fitted onto the corresponding two support rods 3, thereby achieving the lifting effect of the lifting platform 5 by sliding the sliding sleeves 7 outside the support rods 3. This design allows the platform to be placed on the ground, overcoming the problem of significant height differences when transporting welding machines. It also increases the distance between the lifting platform 5 and the top box 4, further improving the ease of transport. In addition, the design of the two connecting frames 6 allows the front and rear sides of the lifting platform 5 to be open, facilitating the lifting and lowering of the corresponding equipment. A rotatable lifting screw 8 is also provided between the two supporting base plates 1 and the top box 4. A lifting threaded sleeve 9 is provided on the outside of the connecting frame 6 and threaded onto the outside of the corresponding lifting screw 8. A drive mechanism 10 is provided at the bottom of the top box 4 to drive the two lifting screws 8 to rotate simultaneously. Thus, the housing drives the two lifting screws 8 to rotate synchronously through the drive mechanism 10, thereby achieving the effect of controlling the lifting and lowering of the lifting platform 5.

[0026] It should be noted that the length of the threaded section of the lifting screw 8 is adapted to the lifting height of the lifting platform 5. In addition, the lifting screw 8 is rotatably mounted through bearings at both ends, and the universal pulley 2 is a universal pulley with a brake structure.

[0027] In a preferred embodiment, the drive mechanism 10 includes a turbine 100 disposed above and outside the two lifting screws 8 respectively. Two bearing seats 101 are symmetrically disposed at the bottom of the top box 4. A drive shaft 102 is rotatably disposed between the two bearing seats 101. Bearings for mounting the drive shaft 102 are disposed in the bearing seats 101. Both ends of the drive shaft 102 pass through the bearing seats 101 and are connected to a worm gear 103 that is connected to the turbine 100. A first drive device 104 is also disposed at the bottom of the top box 4. The first drive device 104 is used to arrange a transmission assembly 105 between the drive shafts 102. The transmission assembly 105 can be a gear transmission structure, a synchronous pulley and synchronous belt transmission structure, or a chain and sprocket transmission structure.

[0028] With this design, the first drive device 104 can drive the transmission shaft 102 to drive the two worm gears 103 to rotate synchronously, thereby using the transmission connection between the worm gears 103 and the turbine 100 to make the two lifting screws 8 rotate synchronously, thus realizing the lifting and lowering of the lifting platform 5.

[0029] Furthermore, the top box 4 is equipped with a movable handle 13 to facilitate movement by staff.

[0030] In the preferred embodiment, the top box 4 is equipped with a storage drawer 15 that can be opened to one side, and a top platform 14 is provided on the top.

[0031] Example 2

[0032] Further explanation in conjunction with Example 1, such as Figure 3-6 As shown in the structure, in order to distinguish the multiple welding machines or other equipment placed on the top of the lifting platform 5 and prevent them from colliding or affecting each other, the top of the lifting platform 5 is provided with a partition 11, which divides the lifting platform 5 into two spaces, left and right.

[0033] In the preferred embodiment, the partition 11 is movably mounted on the lifting platform 5, and an adjustment mechanism 12 for controlling the movement of the partition 11 is provided between the two connecting frames 6, so that the size of the space between the two spaces can be adjusted according to the size of the welding machine placed in the two spaces.

[0034] The lifting platform 5 has two symmetrical horizontal sliding grooves 501, and horizontal sliding rods 502 are installed in the horizontal sliding grooves 501. The two ends of the bottom of the divider 11 are respectively slidably fitted onto the two horizontal sliding rods 502, thereby realizing the effect of the divider 11 being able to slide horizontally.

[0035] In addition, the adjustment mechanism 12 includes a transverse lead screw 120 rotatably disposed between two connecting frames 6. The transverse lead screw 120 is rotatably disposed between the two connecting frames 6 via bearings. A second drive device 121 that is connected to the transverse lead screw 120 is disposed on the outer side of one of the connecting frames 6. A transverse internal thread shaft 122 that is threadedly engaged with the transverse lead screw 120 is disposed on the top of the partition 11.

[0036] With this design, the second drive device 121 can drive the transverse lead screw 120 to move laterally, thereby using the transverse internal thread shaft 122 to drive the partition 11 to move laterally, thus adjusting the size of the left and right spaces of the lifting and placing platform 5 to accommodate welding machines of different sizes.

[0037] It should be noted that both the first drive device 104 and the second drive device 121 are composed of a combination of motor and reducer transmission. In addition, the adjustment mechanism 12 is located at a position that avoids the lifting threaded sleeve 9 and the lifting screw 8.

[0038] In the preferred embodiment, the top of the lifting platform 5 is also provided with a gas cylinder placement rack 17 and a storage battery 18 located behind the partition 11. The length of the lifting platform 5 is greater than the length of the partition 11. The gas cylinder placement rack 17 and the storage battery 18 are specifically located at the position of the lifting platform 5 beyond the partition 11. The gas cylinder placement rack 17 is convenient for placing the gas cylinders needed for welding, and the storage battery 18 is convenient for supplying power to all electrical equipment.

[0039] It should be noted that the electronic control system equipped in this embodiment is all existing technology, and therefore will not be described in detail here.

[0040] In the preferred embodiment, the outer side of the top box 4 is also provided with a hook 19 and a fire extinguisher bracket 16. The hook 19 is convenient for hooking pipes and welding torches, and the fire extinguisher bracket 16 is convenient for installing fire extinguishers.

[0041] In addition, it should be noted that the equipment trolley in this embodiment can be used not only to move welding machines, but also to move other similar equipment.

[0042] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
