[0018] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0019] The present application provides a new energy automobile gearbox differential special lifting appliance, which can be operated by one person, realizes differential hoisting and completes overturning by three angles. ​

[0020] Combination reference Figures 1 to 7 The special lifting tool comprises a lifting frame 1, a crossbeam 2, a fixed jaw arm 3, a guide rail sliding block assembly 4, a movable jaw arm 5, a driving shaft 6, a driving shaft seat 7, a hand crank 8, a handle 9, a driven shaft 10, a driven shaft seat 11, a knob plunger 12, a first clamping jaw 13, a second clamping jaw 14, a door buckle type elbow clamp 15, and a door buckle seat 16.

[0021] The lifting frame 1 is in the shape of a door, and has a lifting lug 1a at the top thereof, which is arranged on the working gravity center vertical line of the lifting tool, so as to balance the lifting tool during hoisting. The working gravity center vertical line refers to the vertical line on which the overall gravity center of the lifting tool is located when the differential is clamped.

[0022] At the bottom of the crossbeam 2, one end is fixedly connected with the fixed jaw arm 3, and below the fixed jaw arm 3 is arranged the driven shaft seat 11, on which the driven shaft 10 is supported, and the driven shaft seat 11 is provided with the knob plunger 12. Correspondingly, the driven shaft 10 is provided with a plurality of positioning holes (not shown in the figure) along the circumference thereof, which are selectively positioned and matched with the knob plunger, so as to limit the turning angle posture of the driven shaft. Preferably, the knob plunger is a spring knob plunger (also known as a spring pull pin).

[0023] At the bottom of the crossbeam 2, the guide rail sliding block assembly 4 is arranged, wherein the guide rail 4a is installed at the bottom of the crossbeam 2, and a pair of sliding blocks 4b are matched with the guide rail 4a, and the pair of sliding blocks 4b are used to install the movable jaw arm 5.

[0024] The movable jaw arm 5 comprises a top connecting plate 51 and a pair of clamping plates 52 fixedly connected to the front and rear sides of the top connecting plate, wherein the driving shaft seat 7 is in the shape of a square block and clamped between the pair of clamping plates 52.

[0025] The driving shaft 6 is supported on the driving shaft seat 7, and the driving shaft 6 is fixedly connected with the hand crank 8. The side of the pair of clamping plates 52 facing the operator is provided with the handle 9, so as to be held by the operator when the hand crank is shaken, so that the lifting tool is not held when the workpiece is turned over.

[0026] The first clamping jaw 13 is fixedly connected with the driving shaft 6, and the second clamping jaw 14 is fixedly connected with the driven shaft 10.

[0027] The door buckle type elbow clamp 15 is arranged on the movable jaw arm 5, and the door buckle seat 16 is fixedly installed on the fixed jaw arm 3 and forms a closed door buckle retaining groove 6a, and the door buckle part 15a of the door buckle type elbow clamp is retained in the door buckle retaining groove 6a to avoid falling out.

[0028] The first jaw 13 and the second jaw 14 hold the planetary gear shaft mounting section 21 of the differential housing 20, the differential housing 20 having a first slot hole 22 and a second slot hole 23 symmetrically arranged on the outer periphery thereof, the first jaw 13 cooperating with the first slot hole 22, and the second jaw 14 cooperating with the second slot hole 23.

[0029] The first jaw 13 comprises a C-shaped jaw seat 131 and a pair of jaw blocks 132 symmetrically arranged on the C-shaped jaw seat 131 above the C-shaped opening facing the workpiece. The second jaw 14 comprises a C-shaped jaw seat 141 and a pair of jaw blocks 142 symmetrically arranged on the C-shaped jaw seat above the C-shaped opening facing the workpiece.

[0030] The pair of jaw blocks 132 are symmetrically arranged on the circumferential two side edges of the first slot hole 22, each of the jaw blocks 132 comprising a slot hole clamping block portion 132a and an outer wall retaining portion 132b, the slot hole clamping block portion 132a extending into the slot hole edge, and the outer wall retaining portion 132b extending on the differential housing outer wall adjacent to the slot hole edge. The other pair of jaw blocks 142 are symmetrically arranged on the circumferential two side edges of the second slot hole 23, and are arranged in the same manner as the pair of jaw blocks 132.

[0031] The workpiece holding process of the present lifting appliance is as follows: when the door-buckle type elbow clamp is opened, the second C-shaped jaw seat is opened relative to the first C-shaped jaw seat, the workpiece is placed into the first and second jaws, when the door-buckle type elbow clamp is buckled, the pair of jaw blocks on the first jaw form a clamping relationship with the first slot hole, and the pair of jaw blocks on the second jaw form a clamping relationship with the second slot hole, thereby realizing the positioning and clamping of the first jaw and the second jaw on the differential.

[0032] When the workpiece is turned over, the U-shaped knob plunger is loosened, one hand holds the hand handle, and the other hand shakes the hand crank, the workpiece is turned over and reaches the predetermined position, the knob plunger is screwed, the driven shaft is positioned and fastened, so that the workpiece is kept at the predetermined position.

[0033] Combined with reference Figures 4 to 6 As can be seen from the different working posture diagrams of the lifting appliance, the lifting appliance can realize three different angle working postures by operating the hand crank and the knob plunger in cooperation. After the jaw clamps the workpiece through the elbow clamp, the button box lifting rope is moved upward (the lifting lug and the lifting rope are connected in advance), then the hand crank is manually operated to rotate the workpiece to the required working posture, the knob plunger is pressed to fix the posture, and finally the workpiece is lifted to the working position.

[0034] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
