Description

Technical Field

[0001] The present invention relates to the technical field of electric power facility maintenance equipment, and in particular to intelligent trolley maintenance equipment. Background Art

[0002] At present, with the popularization of power equipment, switch cabinets are also widely used. The trolley, as the withdrawable part of the switch cabinet, has a large number of main electrical parts on it. The current trolley uses plum blossom contacts as connection terminals and needs to be plugged in, so the contact arms of the trolley are often extended outward. This setting will cause the center of gravity of the trolley to move forward, which is why the trolley is prone to rollover. This also leads to the trolley rolling over easily if the staff does not balance well when pushing and pulling the trolley during maintenance, thereby damaging the plum blossom contacts.

[0003] Current handcarts are heavy and have poor stability, so maintenance equipment is often needed during maintenance. However, current maintenance equipment is often separated from forklifts, and problems are prone to occur during transportation to the maintenance equipment. In addition, current maintenance equipment has problems such as inflexible angle adjustment, insufficient protection for contact arms and contacts, and some maintenance equipment can only complete lifting. Summary of the invention

[0004] The present invention aims at solving the problems in the prior art and proposes an intelligent trolley maintenance device.

[0005] The technical solution adopted by the present invention to solve its technical problem is: An intelligent trolley maintenance device comprises a forklift assembly, wherein the forklift assembly comprises a moving frame and a lifting device, the lifting device is provided with a contact arm protection mechanism for protecting a contact arm, and the moving frame is provided with a trolley maintenance adjustment mechanism; The contact arm protection mechanism is used to connect the independently extended contact arms into a whole through the connecting mechanism, so that the contact arms are mutually stressed, thereby improving the strength of the contact arms; The handcart inspection and adjustment mechanism is used to complete the angle adjustment of the handcart.

[0006] Beneficial effects of the present invention: The device can protect the plum blossom contact of the handcart through the contact arm protection mechanism, balance the center of gravity of the handcart, and connect with the lifting device and the rear baffle through the universal joint to ensure its freedom within a certain range, thereby completing the coordination with the handcart maintenance adjustment mechanism. The handcart maintenance adjustment mechanism is set according to the shape and four corners of the track wheel of the handcart. The car maintenance adjustment mechanism set at the four corners can adjust the angle of the handcart symmetrically or asymmetrically to a certain degree in any direction under the protection and restriction of the contact arm protection mechanism, thereby facilitating maintenance.

DETAILED DESCRIPTION

[0009] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0010] like Figure 1-9 As shown, an intelligent trolley maintenance device includes a forklift assembly, the forklift assembly includes a mobile frame, a lifting device, the lifting device includes a gantry 11, a rear baffle 43, and a fork body 42, the lifting device is provided with a contact arm protection mechanism for protecting the contacts, the mobile frame is provided with a trolley maintenance adjustment mechanism, and the trolley maintenance adjustment mechanism includes a track wheel limiting module.

[0011] like Figures 1 to 3As shown, the lifting device in this embodiment includes a gantry 11 fixedly arranged on a mobile frame, a hydraulic cylinder 13 is arranged in the middle of the gantry 11, a sprocket and a chain cooperating with the sprocket are arranged on the hydraulic cylinder 13, one end of the chain is fixedly arranged on the forklift assembly, and the other end is fixed on the rear baffle 43, sliders are arranged on both sides of the rear baffle 43, the sliders are slidably arranged in the slideways on both sides of the gantry 11 to play a guiding role, a cross plate is also arranged on the lower side of the rear baffle 43, the fork body 42 is slidably arranged on the cross plate, and the trolley body 10 is forked on the fork body 42; the vertical height of the rear baffle 43 can be controlled by the extension length of the hydraulic cylinder 13, and normal movement is ensured by the mobile frame.

[0012] like Figure 5 , Figure 6 As shown, the contact arm protection mechanism in this embodiment includes a transverse protection module and a longitudinal protection module. The transverse protection module includes a transverse screw 32. The left and right sides of the transverse screw 32 have opposite thread settings. The left and right sides of the transverse screw 32 are symmetrically threaded with an outer clamping body 36. A guide rod is fixedly provided at the lower end of the outer clamping body 36. The guide rod is slidably connected to the bottom plate 37. The upper and lower ends of the bottom plate 37 are fixedly connected with side rods 34. The other end of the side rod 34 is fixedly connected to the mounting seat of the transverse motor mounting seat 29; a motor (not shown in the figure) is installed on the transverse motor mounting seat 29. The motor is connected to the transverse screw 32. A connecting rod mounting seat 41 is provided in the middle of the bottom plate 37. A motor (not shown in the figure) is installed on the connecting rod mounting seat 41. The motor is connected to the rotating shaft of the transverse connecting rod 30. The other end of the rotating shaft of the transverse connecting rod 30 is rotatably connected to the support plate 45 on the other side. The support plate 45 passes through the outer clamping body 36 and is fixedly connected to the transverse motor mounting seats 29 on both sides.

[0013] The structure of the outer frame of the longitudinal protection module is the same as that of the transverse protection module, except that two longitudinal connecting rods 31 are arranged in the middle, and the cross-sectional shapes of the transverse connecting rods 30 and the longitudinal connecting rods 31 are elliptical; the transverse connecting rods 30, the longitudinal connecting rods 31 and the surrounding outer clamping bodies 36 form a grid shape, and the transverse protection module and the longitudinal protection module are connected by transverse and longitudinal connecting rods 35 or transverse and longitudinal connecting blocks 38, so that the two form a whole.

[0014] When the contacts of the hand truck need to be protected, the forklift is driven to extend the contact arm into the corresponding grid, and then the motor is controlled to rotate. The motor will drive the transverse screw 32 and the transverse connecting rod 30 to rotate. The rotation of the transverse screw 32 will cause the outer clamping bodies 36 on both sides to move toward each other. The rotation of the transverse connecting rod 30 will abut against the contact arm, thereby connecting the originally independently extended contact arm into a whole through the transverse connecting rod 30 and the longitudinal connecting rod 31. The two constitute the connecting mechanism. At this time, the contact arms can be subjected to force on each other. When external force is applied, not only a single contact arm is subjected to force, but the force is dispersed, thereby improving the strength of the contact arm and reducing the risk of damage. The outer clamping body 36 will correct the position of the hand truck.

[0015] As 7 to Fig. 9 As shown, the trolley maintenance and adjustment mechanism includes an adjusting hydraulic cylinder 14 arranged on the upper part of the supporting leg 12 in the mobile frame, the lower end of the adjusting hydraulic cylinder 14 is ball-connected with a sliding block, the sliding block is slidably connected in the supporting leg 12, and is fixedly connected to a cylinder (not shown in the figure), and the upper ball of the extending end of the adjusting hydraulic cylinder 14 is ball-connected with a rail wheel limiting module.

[0016] In a preferred example, the rail wheel limiting module includes the intermediate plate 15, the middle part of the intermediate plate 15 is through, and the intermediate plate 15 on one side is rotatably connected to a clamping outer ring 23 outside the through hole, and a through groove is annularly distributed in the middle part of the side surface of the clamping outer ring 23, and a clamping rod 22 is rotatably connected to the middle part of the through groove through a pin, and the outer end of the clamping rod 22 is rotatably connected to the connecting column of the intermediate plate 15, and the other end of the clamping rod 22 is rotatably connected to a contact body 24, and a pulling block 25 is fixedly connected to the clamping outer ring 23, and a driven block 28 is rotatably connected to the pulling block 25, and a clamping screw 26 is threadedly connected in the driven block 28, and the other end of the clamping screw 26 extends into the active block 27 and is connected to the motor therein, and the active block 27 is rotatably connected to the connecting seat of the intermediate plate 15. When the track wheel extends into the clamping outer ring 23, the motor can be started to drive the clamping screw 26 to rotate so that the driven block 28 pulls the pulling block 25 to rotate the clamping outer ring 23. The rotation of the clamping outer ring 23 will cause the clamping rod 22 to rotate around the external connection point, thereby clamping the track wheel located in the middle. Since the clamping screw 26 has a self-locking feature, the clamping state can be maintained.

[0017] Furthermore, the track wheel limiting module also includes a self-locking gear 19 arranged on the other side of the intermediate plate 15 and concentric with the clamping outer ring 23. The self-locking gear 19 is annularly distributed with a plurality of inclined sliding grooves, and an inner retracting pin 20 is slidably arranged in the sliding groove. The other end of the inner retracting pin 20 is fixedly connected to the positioning tooth 21, and the positioning tooth 21 is slidably connected in the sliding groove in which it is located. The outer side of the self-locking gear 19 is provided with teeth and meshed with the main driving gear 18, and is connected to the motor through a rotating shaft (not shown in the figure). The outer side of the intermediate plate 15 is also provided with a shell, and the shell is used to protect the overall internal structure. When the track wheel 16 needs to be placed therein, the starting motor drives the intermediate plate 15 to rotate the self-locking gear 19, so that the positioning tooth 21 is driven inward by the inclined groove on the self-locking gear 19 under the limitation of its own sliding groove. When the track wheel 16 is placed, the reverse motor extends the positioning tooth 21, thereby completing the locking of the track wheel 16 to prevent it from sliding out.

[0018] like Figure 1 , Figure 2 and 4 As shown, the trolley in this embodiment includes a trolley body 10 , a contact arm 17 , and a track wheel 16 .

[0019] The working process of the equipment of the present invention is as follows: when the trolley body 10 needs to be inspected and repaired, the equipment is forked and lifted to an appropriate height by the fork body 42, and then the track wheel limiting module is lifted to the same height as the track wheel 16 by the adjusting hydraulic cylinder 14, and then the staff puts the track wheel 16 into the track wheel limiting module, and the track wheel limiting module clamps and locks the track wheel 16. At this time, the adjusting hydraulic cylinder 14 extends synchronously to drive the trolley body 10 to be lifted as a whole, and then the tilt state of the trolley body 10 can be controlled by controlling the adjusting hydraulic cylinders 14 on different sides, and the cylinder connected to the slider at the lower end of the adjusting hydraulic cylinder 14 will drive the adjusting hydraulic cylinder 14 to adapt to the lateral position change, and the ball connector will adapt to the angle change. The contact arms of the trolley body 10 are united under the action of the contact arm protection mechanism to improve the strength of the contact arms, and the setting of the universal joint 44 provides a certain degree of freedom, thereby ensuring that the trolley maintenance and adjustment mechanism can complete the angle adjustment of the trolley, which is convenient for staff to inspect and repair. When the angle is adjusted, the fork body 42 plays a protective role to avoid accidents caused by the trolley falling.
