The square lifting support rod 12 is slidably installed in the support sleeve 11 and is threadedly connected with the lead screw 13. The adjusting rod 14 is rotatably installed at the lower part of the support sleeve 11 and is drivingly connected with the lower end of the lead screw 13 through a worm and gear structure.
[0006] Preferably, a limiting slot 3 is provided in the pit, which intersects with the strip-shaped placement slot 2 and is close to the connecting end of the support sleeve 11. A limiting rod 4 is rotatably connected in the middle of the limiting slot 3, and the limiting rod 4 is rotatably clamped on the strip-shaped placement slot 2 to block the vertical support component 1.
[0007] Preferably, a buffer 8 is provided in the pit.
[0008] The utility model discloses an advantageous effect is: the utility model discloses the support part of adjustable height's setting supports in the bottom of car, and the car is supported to avoid the car from falling, causes the safety accident, makes the higher security when the maintenance personnel carries out the maintenance to the car bottom, and the support part can be placed in the strip placement groove through the rotation, thereby when the car bottom maintenance is completed, needs to the equipment in the bottom pit and carries out the maintenance, and the support part will not influence the maintenance work of the maintenance personnel. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 2 It is the structure schematic diagram of the support part.
[0011] Fig. 3 It is the cross section structure three -dimensional schematic diagram of the support part. DETAILED DESCRIPTION
[0012] In order to make the purpose, technical scheme and beneficial effect of the utility model more clearly, the preferred embodiment of the utility model will be explained in detail below, to facilitate the understanding of technical personnel.
[0013] As Figs. 1-3The utility model provides a elevator car bottom overhauling device for elevator maintenance, the overhauling device is installed in the pit, is composed of a plurality of support components 1 installed in the pit, the bottom end of support component 1 is rotatably installed in one end of the strip placement groove 2 arranged in the pit, and support component 1 can be placed horizontally in the strip placement groove 2 by rotating, the support component 1 includes support sleeve 11, square lifting support rod 12, screw rod 13, adjusting rod 14, the support sleeve 11 is the square tubular structure of upper end opening, and the lower end is rotatably installed in one end of the strip placement groove 2, the lower end of screw rod 13 is rotatably installed in support sleeve 11, square lifting support rod 12 is slidably installed in support sleeve 11 and is screw connected with screw rod 13, adjusting rod 14 is rotatably installed in the lower part of support sleeve 11 and is drivingly connected with the lower end of screw rod 13 through worm and gear structure, when overhauling the car bottom, a plurality of support components 1 installed in the pit support the car bottom, pull out support component 1 from the strip placement groove 2, after rotating one end, present vertical state, then rotate adjusting rod 14, drive screw rod 13 to rotate through worm and gear mechanism, screw rod 13 is screw connected with square lifting support rod 12, thereby drive square lifting support rod 12 to ascend in support sleeve 11 and top in the car bottom, support the car, thereby avoid the car to fall, cause safety accident, make the overhauling personnel have higher security when overhauling the car bottom, and simultaneously, support component 1 can be placed in the strip placement groove 2 after rotating, thereby when overhauling the equipment in the pit after overhauling the car bottom, support component 1 will not influence the overhauling work of overhauling personnel.
[0014] The pit is provided with the limiting groove 3 close to the connecting end of support sleeve 11 and intersecting with the strip placement groove 2, the limiting rod 4 is rotatably connected in the middle of limiting groove 3, and the limiting rod 4 is rotatably clamped on the strip placement groove 2 and blocks the vertical support component 1, when support component 1 is pulled out from the strip placement groove 2 and presents vertical state, rotate the limiting rod 4 and clamp in the limiting groove 3 on the strip placement groove 2, thereby block support component 1, avoid support component 1 to fall, improve the stability and security of support component 1 to the car support.
