Description

Technical Field

[0001] The utility model relates to the technical field of hoisting operations, in particular to a valve chamber hoisting tool. Background Art

[0002] The top entrance of the shut-off valve chamber is usually located near the wall, and there are protruding steps on the edge of the entrance. Due to the interference of the wall and the steps, it is impossible to set up a gantry for hoisting heavy objects such as battery packs and shut-off valves. In the past, when carrying heavy objects such as battery packs and shut-off valves in places such as the shut-off valve chamber, a tripod was usually set up at the top entrance of the valve chamber, and the hoisted battery packs, shut-off valves, etc. were placed on one side of the entrance. When lifting heavy objects, the heavy objects need to be swung to the top of the top entrance of the valve chamber in a suspended state, or swung to one side from the top entrance of the valve chamber. This process will generate centrifugal force on the tripod, and there is a risk of the tripod tipping over. In addition, when using a tripod for hoisting operations, in order to reduce the shaking of the tripod caused by the swinging of the heavy object, three people are required to support the tripod separately, and an additional person is required to support the heavy object, which has high labor costs.

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] This utility model refers to Figure 1-2 .

[0031] The utility model provides a valve chamber lifting tool, including a slide rail beam 1, support columns are provided at both ends of the slide rail beam 1, the length of the support columns is adjustable, a base 2 is provided at the lower end of the support column, and the two ends of the base 2 can be used to overlap on both sides of the top entrance of the valve chamber; a lifting frame 3 is provided on the slide rail beam 1, the lifting frame 3 can move along the length direction of the slide rail beam 1, and a crane 4 is provided on the lifting frame 3.

[0032] principle:

[0033] When carrying heavy objects such as battery packs and shut-off valves in the valve chamber, place the base 2 at the lower end of one support column on the ground, and overlap the base 2 at the lower end of the other support column on both sides of the top entrance of the valve chamber, so that half of the slide rail beam 1 is directly above the top entrance of the valve chamber, and the other half is located on the side of the top entrance of the valve chamber; at the same time, adjust the length of the two support columns until the slide rail beam 1 is in a horizontal state. When hoisting heavy objects, the heavy objects to be hoisted into the valve chamber are transported to the side of the top entrance of the valve chamber with a trolley, and the hoisting frame 3 is moved above the heavy objects. After the crane 4 drops the heavy objects, the hoisting frame 3 slowly moves to the top entrance of the valve chamber, and finally the crane 4 slowly lowers the heavy objects. When hoisting heavy objects out of the valve chamber, the above process is reversed.

[0034] Preferably, the hoisting frame 3 and the crane 4 can also be replaced by a self-propelled electric hoist.

[0035] By adopting the utility model, a base 2 is overlapped on both sides of the top entrance of the valve chamber, and the other base 2 is placed on the ground. At the same time, the lengths of the two supporting columns are adjusted to make the slide rail beam 1 in a horizontal state, and the hoisting frame 3 and the crane 4 slowly move along the slide rail beam 1, thereby realizing the safe hoisting in and out of the valve chamber; effectively avoiding the large swing of the heavy object when it is hoisted, and improving the safety; only one person is needed to operate the hoisting frame 3 and the crane 4, thereby reducing the labor cost.

[0036] Further, such as Figure 2 As shown: the support column includes a support tube 5 and a lead screw 6. A shell 7 is provided on the upper part of the support tube 5. A worm wheel 8 and a worm 9 are rotatably connected inside the shell 7. The worm 9 and the worm wheel 8 are meshed with each other. The lead screw 6 coaxially penetrates the worm wheel 8 and is connected to the worm wheel 8 by a thread. The upper end of the lead screw 6 is connected to the slide rail beam 1, and the lower end of the support tube 5 is connected to the base 2.

[0037] The worm wheel 8 is driven to rotate by the worm 9, and the worm wheel 8 rotates relative to the lead screw 6, thereby driving the lead screw 6 to move axially, thereby realizing the length adjustment of the support column; through the combination of the worm 9 pair and the lead screw 6 pair, the thread of the worm wheel 8 provides reliable support for the axial force of the lead screw 6, and at the same time, the resistance to operating the worm 9 is small, and the worm 9 is easy to fix after the adjustment is completed.

[0038] Furthermore, the lower end of the lead screw 6 extends into the support tube 5 and is provided with a guide block 10. The guide block 10 is cylindrical and contacts the inner wall of the support tube 5. The support tube 5 is a cylinder.

[0039] Note: The lead screw 6 does not rotate, and the guide block 10 and the lead screw 6 can be connected by threads.

[0040] The inner space of the support tube 5 is fully utilized, and the occupied volume is small; the guide block 10 is used to avoid bending and deformation of the lead screw 6, thereby increasing the service life.

[0041] Furthermore, one end of the worm 9 extends out of the housing 7 and is connected to a first motor 11 , and the first motor 11 is fixed on the housing 7 .

[0042] The worm 9 is driven by the first motor 11, so that the length of the support column can be adjusted easily. The operation is convenient and the installation work can be completed by one person.

[0043] Further, such as Figure 1 As shown: the hoisting frame 3 includes a sliding frame 12, the bottom of the sliding frame 12 is connected to a mounting frame 13 by bolts, and the crane 4 is fixed on the mounting frame 13; the sliding frame 12 is provided with a roller and a second motor 14, the roller can roll on the slide rail beam 1, and the output end of the second motor 14 is connected to the roller.

[0044] The second motor 14 drives the roller to roll on the slide rail beam 1, thereby driving the slide frame 12 to move on the slide rail beam 1, which is easy to operate.

[0045] Furthermore, the roller includes a first roller 15 and a second roller 16; the slide rail beam 1 is an I-beam, and at least two first rollers 15 are provided in the grooves on both sides of the I-beam, and the first rollers 15 can roll along the lower side walls of the grooves; the second roller 16 is located at the top of the I-beam and can roll along the top of the I-beam; the output end of the second motor 14 is connected to one of the first rollers 15 or the second rollers 16.

[0046] The first roller 15 is arranged in the groove of the I-beam, so the balance is good; the first roller 15 and the second roller 16 jointly support the gravity of the crane 4, so as to make full use of the plane of the I-beam, increase the contact area, avoid stress concentration, and the hoisting frame 3 has good operating stability.

[0047] Furthermore, a mounting plate 17 is provided at the upper end of the support column, and the mounting plate 17 is attached to the bottom of the slide rail beam 1 and connected by bolts.

[0048] Easy to install, the support column can be disassembled when not in use, which is convenient for storage and takes up little space.

[0049] Furthermore, it also includes a first rib plate 18 , one end of which is connected to the upper portion of the support column, and the other end of which is connected to the bottom of the slide rail beam 1 .
