TECHNICAL FIELD

[0001] The utility model belongs to the technical field of overhauling equipment, and relates to a portable belt pulley mounting device for narrow space. BACKGROUND

[0002] For large equipment with a transmission part installed at the bottom of the equipment and a belt transmission, replacement or mounting and dismounting operation of the belt pulley is extremely difficult, and the following problems mainly exist in overhauling operation.

[0003] 1. The belt pulley is heavy, and dismounting and mounting operation in a narrow space is difficult, at least three people need to adopt a squatting posture to lift the belt pulley by hand for lifting or lowering operation, effective tools cannot be used for assisting operation, manual lifting and adjustment twice have exhausted physical strength, and the whole overhauling operation takes a long time.

[0004] 2. Manual lifting is unstable, and manual installation cannot guarantee the installation precision of the belt pulley.

[0005] 3. The operation space for replacement or mounting and dismounting is narrow, the belt pulley is heavy, and the operation personnel are limited in squatting posture operation, the belt pulley has a falling risk, the operation personnel cannot adjust the posture and avoid quickly in the narrow space when falling, and there is a safety hazard.

[0006] Therefore, a new mechanical device is needed to replace manual replacement or mounting and dismounting operation of the belt pulley. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims at the problems in the prior art, and provides a portable belt pulley mounting device for narrow space, which solves the problem of difficult dismounting and mounting operation of the belt pulley in a narrow space.

[0008] Therefore, the utility model adopts the following technical scheme:

[0009] A portable belt pulley mounting device for narrow space, comprising a base, a vertical jack is arranged at the top of the base, a bracket base is arranged above the hydraulic rod of the vertical jack, and the two are detachably connected, a lifting bracket is arranged at the top of the bracket base and fixedly connected with the bracket base, three symmetrical supporting rods are arranged at the side of the lifting bracket, the supporting rods are provided with clamps and movably connected with the lifting bracket, and a center hole in a concave shape is arranged in the middle of the lifting bracket.

[0010] Further, the three clamps are in a clamping shape.

[0011] Further, the clamp is horizontally arranged, the cross section of the clamp is in an arc shape, and the opening faces the lifting bracket.

[0012] Further, the base bottom is provided with a plurality of universal wheels with limiting function.

[0013] The utility model discloses the beneficial effect lies in:

[0014] The utility model discloses in the use process, changed the mode that operating personnel entered the narrow space of equipment bottom and carried out the work, reduced the security risk that operating personnel took the squatting posture when installing the belt pulley, reduced the accident rate of mechanical injury, thereby the operating personnel quantity required for replacing, overhauling the belt pulley reduced, saved the labor, shortened the belt pulley overhauling time, improved production efficiency. BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 It is the overhead structure schematic diagram of the utility model;

[0016] Figure 2 It is the main view structure schematic diagram of the utility model.

[0017] In the drawing, 1 is a lifting support, 1a is a support rod, 1b is a hoop, 2 is a vertical jack, 3 is a base, 4 is a universal wheel, 5 is a support base, 6 is a center hole. DETAILED DESCRIPTION

[0018] The technical scheme of the utility model will be described in connection with the drawings and implementation methods.

[0019] As Figure 1 And 2 Shown, a kind of portable belt pulley installation device for narrow space, including base 3, the base 3 bottom is equipped with a plurality of universal wheels 4 with limiting function;Base 3 top is equipped with vertical jack 2, and the hydraulic rod of vertical jack 2 is equipped with support base 5, and the both are detachably connected.

[0020] The top of support base 5 is equipped with lifting support 1, and the both are fixedly connected, and the side of lifting support 1 is equipped with three support rods 1a symmetrically arranged, and support rod 1a is equipped with hoop 1b, specifically, hoop 1b is horizontally arranged, and its cross section is arc-shaped, and the opening is towards lifting support 1, and the three hoops 1b are in the form of embracing, suitable for installing belt pulley of different specifications;Each hoop 1b is movably connected with corresponding support rod 1a, and the middle of lifting support 1 is equipped with center hole 6 in the form of concave down, and its setting purpose is to facilitate the installation of belt pulley in place, avoid the shaft head to be dead and unable to install belt pulley in place.

[0021] The use process of the utility model is as follows:

[0022] First, the load-bearing base support 3 with universal wheel 4 is placed on a solid support surface, the jack 2 is placed at the geometric center of the heavy base support 3, the belt pulley lifting support base 5 is installed above the jack 2, different specifications of belt pulley lifting support 1 are installed above the lifting support base 5, the vertical height of the jack 2 and the horizontal position of the load-bearing base support 3 are adjusted, the device is correctly placed under the belt pulley to be installed or disassembled, then the three slidable ring clamps 1b are adjusted for limiting, the three together realize ring clamping of the belt pulley, preventing the belt pulley from slipping during installation or disassembly, then the jack 2 is lifted or lowered, the installation or disassembly of the belt pulley is completed, finally the entire device is pulled out of the bottom of the equipment, two people can complete the work, improving the safety and efficiency of the belt pulley work.
