[0031] The utility model discloses a lifting tool suitable for use in a narrow space, especially for lifting motors and material pumps inside a grinder. Due to the narrow space inside the grinder, during the process of disassembling or carrying motors and material pumps, construction workers cannot enter the grinder to carry them, which not only increases the construction time, but also causes waist injuries to construction workers when carrying motors and material pumps, increasing manpower and safety risks.

[0032] like Figure 1 As shown, the utility model discloses a lifting tool suitable for a narrow space, comprising a support frame 1, a suspension rod 2 located above the support frame 1, the support frame 1 and the suspension rod 2 are movably connected via a connecting seat 3, one end of the suspension rod 2 is connected to a suspension connector 21, and the other end of the suspension rod 2 is provided with a lifting handle 22, that is, the suspension rod 2 is provided with a lifting handle 22 at the rear end of the connecting seat 3, and the suspension rod 2 is provided with a suspension connector 23 at the front end of the connecting seat 3. The suspension rod 2 is configured as a suspension lifting part at the rear end of the connecting seat 3, and the support frame 1 uses the connecting seat 3 as a fulcrum to provide a lever support force for the suspension rod 2. The suspension connector 21 can be detachably connected to a lifting fixture, and the lifting fixture is used to clamp the motor or material pump. When lifting is required, the lifting handle 22 is gently pressed to lift the motor or material pump clamped by the lifting fixture. The support frame 1 is connected with rollers at the bottom. After the motor or the material pump is hoisted, the motor or the material pump can be moved to a suitable position by pushing, which is convenient and labor-saving.

[0033] In order to further reflect the labor-saving effect of the lever, the length ratio of the sling connection part 23 to the sling lifting part is 1:2.5~3.5. In some examples, the length ratio of the sling connection part 23 to the sling lifting part is 1:3. In order to facilitate the adjustment of the length ratio between the sling connection part 23 and the sling lifting part, the suspension rod 2 is provided with a plurality of through holes, and the plurality of through holes are spaced at a set distance, which can be set at about 50 cm, or can be flexibly set according to the length of the suspension rod 2. The connecting seat 3 is axially connected to the through hole, for example, the connecting seat 3 has a pair of hanging ears, and the pair of hanging ears are respectively attached to the two sides of the suspension rod 2, and the hanging ears are provided with an axial hole for the bolt to pass through. After the bolt passes through the axial hole, it passes through the through hole on the suspension rod 2, and the connecting seat 3 and the suspension rod 2 are fixedly connected, and due to the effect of the axial connection, the suspension rod 2 can move up and down at the connecting seat 3, so that the connecting seat 3 acts as a lever fulcrum. In order to adjust the position of the lever fulcrum, the connecting seat 3 is connected to different through holes through an axis, so as to flexibly adjust the length of the sling connecting part and the sling lifting part.

[0034] In order to facilitate the use at the construction site and improve the utilization rate of the lifting tools, the utility model discloses a lifting tool suitable for a small space. Different lifting clamps can be selected to install motors of different weights or different types of motors. The following is an explanation taking three commonly used lifting clamps as examples.

[0035] like Figure 2a and Figure 3a The first type of lifting fixture shown can be used to hook motors weighing less than 200kg, and can also be used to hook horizontal motors. The length of the lifting fixture connection part is recommended to be about 450cm. The lifting fixture includes a hanging chain and a hook that are connected to each other. The hanging chain connection part 24 is provided on the hanging fixture connection part 23 of the hanging rod 2.

[0036] like Figure 2b and Figure 3b The second type of lifting fixture shown in the figure can be used to lift motors weighing less than 140kg, and can also be used to lift vertical motors. The length of the lifting fixture connection part 23 is recommended to be about 790cm. The lifting fixture includes a connecting column 40, and the connecting column 40 is connected to the lifting fixture connection head 21 through a flange. Figure 4As shown, a flange is fixedly installed on the side of the connecting column 40, and another matching flange is also fixedly installed on the sling connector 21. A flange gasket is added between the two flanges, and then the two flanges are tightened with bolts to make them tightly combined to form a detachable joint. The top of the connecting column 40 is connected to an annular enclosure 41. The annular enclosure 41 is fixed to the connecting column, and the annular enclosure 41 itself is bolted into an approximately circular shape. The end of the connecting column 40 is connected to a concave clamp seat 42, and the concave clamp seat 42 includes at least two support tongues 43 protruding from the concave clamp seat 42. The concave clamp seat 42 and the support tongue 43 can be formed in one piece. The support tongue 43 is used to support the motor shaft of the motor, and the annular enclosure 41 is used to prevent the motor from tilting. When hoisting a vertical motor, the motor shaft is fixed on the extended support tongue 43, and the annular enclosure 41 above protects the motor to prevent it from tilting. The construction worker stands on one side of the hoisting handle 22 and gently applies downward force, and the motor is hoisted. Then, it can be moved at will by rolling on the rollers, reducing the risk of manual transportation.

[0037] like Figure 2c and Figure 3c The third type of lifting fixture shown in the figure can be used to lift motors weighing less than 120kg, and can also be used to lift the pump head of a grinder. The length of the lifting fixture connection part is recommended to be 800cm. The lifting fixture includes a connecting column 40, and the connecting column 40 is connected to the lifting fixture connection head 21 through a flange. Figure 5 As shown. The end of the connecting column 40 is connected to a supporting platform 44 of a rectangular frame structure, and the supporting platform 44 is connected to the connecting column 40 through a connecting inclined plate 45. When hoisting the crusher pump head, the crusher pump head is fixed on the supporting platform 44, and the supporting platform 44 drags the crusher material pump. The construction worker stands on one side of the hoisting handle 22 and gently pushes downward, and the motor is hoisted. Then, the crusher material pump can be moved out of the narrow space in the crusher by rolling the roller, reducing the risk of manual handling.

[0038] In order to improve the stability of the support frame, the support frame 1 is a triangular pyramid support frame. In some examples, the support frame 1 includes a support base column 10, a first support inclined column 11, and a second support inclined column 12 connected head to tail, respectively. The support base column 10, the first support inclined column 11, and the second support inclined column 12 form a triangular support structure. The first support inclined column 11 is connected to a first auxiliary support inclined column 13, and the second support inclined column 12 is connected to a second auxiliary support inclined column 14. The first auxiliary support inclined column 13 and the second auxiliary support inclined column 14 are symmetrical. The bottom ends of the first support inclined column 11, the second support inclined column 12, the first auxiliary support inclined column 13, and the second auxiliary support inclined column 14 are respectively connected to rollers, and the four rollers are located in the same plane to jointly realize the free movement of the support frame 1.

[0039] When used on the construction site, the lifting tool is generally designed using the principle of leverage, and a design drawing of the lifting tool is drawn, including a connection diagram with the horizontal motor, grinder pump, and vertical motor, and the load-bearing capacity of the motor lifting tool is calculated by the stress of the steel structure. The lifting tools in this embodiment are all made of steel structure, and the rigidity of the steel structure is used to make lifting tools with strong load-bearing capacity. The construction site makes the lifting tools according to the design drawing, and also makes three kinds of lifting clamps, which can be disassembled at will through the flange structure connection, so that they can be flexibly replaced and adjusted for different environments of different motor sites. Four universal wheels with brakes are also needed on site to enable them to be moved and transported at will, reducing the risk of manual handling.

[0040] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technology in the field can make many modifications and changes according to the concept of the utility model without creative work.
