Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of hoisting, and in particular to a motor hoisting tool. Background Art
[0002] The motor, also known as the starter, rotates the starter rotor by rotating the energized coil in the magnetic field. The small gear on the rotor rotates the engine flywheel, which in turn drives the crankshaft to start the vehicle. The two component innovations, the new low-cost spark plug with a ceramic core base and the starter, laid the technical foundation for the development of automobiles.
[0003] However, after the motor is assembled, it needs to be moved to a designated location through a lifting device. Multiple hooks are connected to the lifting rope of the lifting device to lift the motor. The motor will shake during the movement, and the shaking will increase the strength of the lifting rope on one side. When the shaking angle is too large, the lifting rope on one side will be subjected to greater force. When the force exceeds the maximum force that the lifting rope can withstand, it will break, causing the motor to fall and cause irreparable losses. Therefore, a motor lifting tool is proposed to solve these problems. Summary of the Invention
[0004] The object of the present invention is to provide a motor hoisting tool to solve the problem of the rope breaking due to excessive stretching caused by the lack of a limiting mechanism.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a motor lifting tool, comprising a connecting plate, a pneumatic hoist is fixedly installed at the center of the bottom of the connecting plate, hand hoists are fixedly installed around the bottom of the connecting plate, four hand hoists and pneumatic hoists are fixedly installed with lifting ropes at the bottom, five lifting ropes are fixedly installed with hook rods at the bottom, a lifting rod is detachably installed at the bottom of the hook rod, a connecting hole is opened through the bottom of one side of the lifting rod, a limiting sleeve is movably installed on the top of the lifting rod, a connecting rod is movably sleeved inside the limiting sleeve, and the top of the connecting rod is fixedly connected to the bottom of the connecting plate.

[0007] As a preferred technical solution of the present invention, a second lifting lug is fixedly installed at the cross center of the top of the boom, and first lifting lugs are fixedly installed at the four ends of the top of the boom.
[0008] As a preferred technical solution of the present invention, the hook rods at the bottom of the four hand hoists are hinged to the four first lifting ears, and the hook rod at the bottom of the pneumatic hoist is also hinged to the second lifting ears.
[0009] As a preferred technical solution of the present invention, the load of the first lifting lug is 5-6 tons, and the load of the second lifting lug is 20-30 tons.
[0010] As a preferred technical solution of the present invention, the approved tonnage of the hand chain hoist is 5-6 tons, and the approved tonnage of the pneumatic hoist is 20-30 tons.
[0011] As a preferred technical solution of the present invention, reinforcing elbow plates are fixedly installed on both sides of the middle part of the four ends of the boom, and the reinforcing elbow plates are used to increase the supporting strength of the boom.
[0012] As a preferred technical solution of the present invention, connecting blocks are fixedly installed in the middle of the four ends of the top of the boom, the number of the limiting sleeves is also four and grooves are provided at the bottom, and through holes are provided on one side of the groove and the connecting block, and the limiting rods are installed through the inside.
[0013] As a preferred technical solution of the present invention, a sliding groove is provided through the top of one side of the limiting sleeve rod, and a placement groove is provided through the top of the limiting sleeve rod.
[0014] As a preferred technical solution of the present invention, a limiting slider is fixedly installed at the bottom of the connecting rod, and the limiting slider is used in conjunction with the sliding groove.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The present invention wraps a strap around the motor to be hoisted, fixes the strap in the connecting hole, and pulls the pneumatic hoist and the hand hoist to drive the motor to move. Due to inertia during movement, the motor will shake, and the connecting rod will make relative movement inside the limit sleeve when shaking. When the lifting rope shakes within a certain range, the movement of the limit sleeve and the connecting rod does not affect the slight shaking of the lifting rope. When the shaking angle is too large, the limit sleeve rotates, so that the internal connecting rod moves inside the limit sleeve. When the limit slider touches the bottom of the slide groove, the limit sleeve cannot bend, and the shaking range of the lifting rope can be limited, thereby achieving the effect of limiting the lifting rope to prevent the lifting rope from being excessively stretched and broken.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0023] See also Figure 1-4 The present invention provides a technical solution: a motor lifting tool, including a connecting plate 1, a pneumatic hoist 2 is fixedly installed at the center of the bottom of the connecting plate 1, and hand hoists 3 are fixedly installed around the bottom of the connecting plate 1. Four hand hoists 3 and the pneumatic hoist 2 are fixedly installed at the bottom with a lifting rope 4, and the five lifting ropes 4 are fixedly installed at the bottom with a hook rod 5. A lifting rod 8 is detachably installed at the bottom of the hook rod 5, and a connecting hole 81 is opened through the bottom of one side of the lifting rod 8. A limiting sleeve rod 10 is movably installed on the top of the lifting rod 8, and a connecting rod 11 is movably sleeved inside the limiting sleeve rod 10. The top of the connecting rod 11 is fixedly connected to the bottom of the connecting plate 1.
[0024] Among them, the suspension rod 8 is cross-shaped, which increases the number of force application points of the suspension and increases stability. There are four connecting holes 81, and the spacing between the four connecting holes 81 and the middle of the suspension rod 8 is equal, so that when the four connecting holes 81 are suspended, the force applied is the same, and there will be no situation where one side is subjected to excessive force.
[0025] Among them, a second lifting ear 7 is fixedly installed at the cross-shaped center of the top of the boom 8. The load of the second lifting ear 7 is 20-30 tons. The approved tonnage of the pneumatic hoist 2 is 20-30 tons. The hook rod 5 at the bottom of the pneumatic hoist 2 and the second lifting ear 7 are also hinged to each other. The middle part of the cross-shaped boom 8 is subjected to the greatest force. The load mass of the second lifting ear 7 should be greater than four times the load mass of the first lifting ear 6.
[0026] Among them, the four ends of the top of the lifting rod 8 are fixedly installed with first lifting ears 6, the hook rods 5 at the bottom of the four hand hoists 3 are hinged to each other with the four first lifting ears 6, the load of the first lifting ears 6 is 5-6 tons, and the approved tonnage of the hand hoist 3 is 5-6 tons.
[0027] Among them, reinforcing elbow plates 9 are fixedly installed on both sides of the middle part of the four ends of the suspension rod 8. The reinforcing elbow plates 9 are used to increase the supporting strength of the suspension rod 8. Connecting blocks 12 are fixedly installed in the middle part of the four ends of the top of the suspension rod 8. There are four limit sleeves 10 and grooves are provided at the bottom. A through hole is provided on one side of the groove and the connecting block 12, and a limit rod 102 is installed inside the limit sleeve 10 so that the limit sleeve 10 can rotate. When the suspension rope 4 shakes, the limit sleeve 10 rotates, so that the internal connecting rod 11 moves inside the limit sleeve 10. When the limit slider 111 touches the bottom of the slide groove 101, the limit sleeve 10 cannot bend, thereby limiting the shaking amplitude of the suspension rope 4.
[0028] Among them, a slide groove 101 is opened through the top of one side of the limit sleeve rod 10, and a placement groove is opened through the top of the limit sleeve rod 10. The size of the placement groove is larger than the size of the connecting rod 11. A limit slider 111 is fixedly installed at the bottom of the connecting rod 11. The limit slider 111 is used in conjunction with the slide groove 101, and the difference between the height value of the limit slider 111 and the thickness value of the slide groove 101 is equal to the difference between the width value of the inner wall of the limit sleeve rod 10 and the width value of the connecting rod 11, so that when subjected to tension, the connecting rod 11 will make relative movement inside the limit sleeve rod 10. When the lifting rope 4 shakes within a certain range, the movement of the limit sleeve rod 10 and the connecting rod 11 does not affect the slight shaking of the lifting rope 4.
[0029] Working principle: When in use, first wrap the strap around the motor to be hoisted, fix the strap in the connection hole 81, and then connect the hook rod 5 with the first lifting ear 6 and the second lifting ear 7. The load of the second lifting ear 7 is four times that of the first lifting ear 6. When the motor moves, the offset force will deviate, and the tension on the middle second lifting ear 7 will increase, and the effect of the second lifting ear 7 being damaged by gravity will not occur. When the pneumatic hoist 2 and the hand hoist 3 are pulled to drive the motor to move, the inertia during the movement The motor will shake, and the connecting rod 11 will make relative movement inside the limit sleeve 10 when shaking. When the rope 4 shakes within a certain range, the movement of the limit sleeve 10 and the connecting rod 11 will not affect the slight shaking of the rope 4. When the shaking angle is too large, the limit sleeve 10 rotates, so that the internal connecting rod 11 moves inside the limit sleeve 10. When the limit slider 111 touches the bottom of the slide groove 101, the limit sleeve 10 cannot bend, and the shaking range of the rope 4 can be limited.
