Description
Technical Field
[0001] The utility model relates to the technical field of vacuum circuit breakers, and more specifically to a trolley-type vacuum circuit breaker transport trolley. Background Art
[0002] The vacuum circuit breaker installed in the cabinet is generally removable, such as fixing the vacuum circuit breaker on a chassis with two rolling wheels and a universal wheel, that is, a trolley-type vacuum circuit breaker. A guide rail is installed on the bottom surface of the cabinet body, and the roller of the trolley-type vacuum circuit breaker rolls in the groove of the guide rail and guides it into the groove, so that the trolley-type vacuum circuit breaker is very convenient to push and remove in the switch cabinet. When the trolley-type vacuum circuit breaker is moved in and out of the switch cabinet, it is usually necessary to equip a special trolley-type vacuum circuit breaker transport trolley to facilitate the transfer of the trolley-type vacuum circuit breaker. Since the ground in the distribution room and the foundation channel steel of the fixed switch cabinet are not on the same horizontal plane, the foundation channel steel surface is higher than the ground, and the height difference between the foundation channel steel surface and the ground in different distribution rooms is different, in order to adapt to the requirements of different distribution rooms, the existing technology has designed and developed a transport trolley with adjustable height, which has greatly improved the convenience of transportation and installation.
[0003] However, after the transport trolley in the prior art is lifted into place, the removal end thereof can often only be flush with the foundation channel steel of the fixed switch cabinet. There is an obvious gap between the transport trolley and the cabinet body and lacks effective positioning, resulting in unstable movement in and out of the trolley-type vacuum circuit breaker. As a result, when removing the trolley-type vacuum circuit breaker from the transport trolley, it is often necessary to move very carefully, which is very inconvenient to operate.

Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0028] The utility model is implemented as follows Figures 1 to 6 As shown in the figure, a trolley-type vacuum circuit breaker transport trolley includes a frame 1, a pushing mechanism 2, a lifting mechanism 3 and a support plate 4. The pushing mechanism 2 is arranged on the frame 1 to drive the frame 1 to move, the support plate 4 is arranged on the lifting mechanism 3, and the lifting mechanism 3 is arranged on the frame 1 to drive the support plate 4 to rise and fall; two left and right corresponding baffles 5 are arranged on the support plate 4, and a limited accommodating space for accommodating the trolley-type vacuum circuit breaker 100 to move in and out is formed between the two baffles 5 and the support plate 4; the rear ends of the two baffles 5 extend backward and are located behind the support plate 4, and the rear ends of the two baffles 5 are also provided with positioning bayonet 50; the two baffles 5 are also provided with lock holes 501 for the lock tongue 101 of the trolley-type vacuum circuit breaker 100 to cooperate and insert.
[0029] The known trolley type vacuum circuit breaker 100 is a vacuum circuit breaker 10 arranged on a chassis 11, and the vacuum circuit breaker 10 is conveniently moved by the arrangement of the chassis 11. Among them, the chassis 11 is provided with rollers 102, such as the rollers 102 are arranged on the left and right sides of the chassis 11, and the number of rollers 102 on each side is not less than two, so as to facilitate movement. Moreover, the lock tongue 101 is also correspondingly arranged on the left and right sides of the chassis 11, and the position of the lock tongue 101 corresponds to the lock hole 501 on the same side for easy insertion.
[0030] Specifically, in this embodiment, the two baffles 5 each include an integrally connected bottom plate 51 and a side plate 52, and the bottom plate 51 and the side plate 52 are both arranged along the front-back direction of the support plate 4, and the shape of the integrally connected bottom plate 51 and the side plate 52 is L-shaped. The two bottom plates 51 are both fitted and fixed to the upper surface of the support plate 4, for example, they are installed and fixed by fasteners such as screws. The two bottom plates 51 are correspondingly located at the left and right edges of the upper surface of the support plate 4, and the two side plates 52 are correspondingly located at the outer edges of the bottom plates 51 on the same side, that is, the two bottom plates 51 are arranged parallel and oppositely on the same horizontal plane, and the two side plates 52 are opposite and correspondingly located at the left and right side edges of the support plate 4, so that the L-shaped recesses formed between the two bottom plates 51 and the side plates 52 on the same side are opposite. Furthermore, a limited accommodation space is formed between the two side plates 52 and the upper surface of the support plate 4, and the front and rear sides of the limited accommodation space are both open to accommodate the trolley-type vacuum circuit breaker 100 and facilitate the trolley-type vacuum circuit breaker 100 to move in and out. Furthermore, the rear ends of the two bottom plates 51 extend out of the limiting accommodation space and are relatively located behind the support plate 4 . Accordingly, the rear ends of the two bottom plates 51 are provided with positioning bayonet holes 50 located behind the support plate 4 .
[0031] The rear ends of the two bottom plates 51 are provided with extension plates 511 integrally connected to the bottom plates 51 on the same side, and positioning slots 50 are formed between the outer side surfaces of the two extension plates 511 and the rear end surfaces of the connected bottom plates 51. Furthermore, the outer side surfaces of the two extension plates 511 (i.e., the side surfaces of the two extension plates 511 facing away from each other) are both set as inclined surfaces, such as Figure 3 As shown in the figure, the shapes of the two extension plates 511 are both right-angled trapezoids, and an angle is formed between the outer side surfaces of the two extension plates 511 and the rear end surface of the connected bottom plate 51, specifically, the angle is an obtuse angle; such a configuration helps that after the pallet 4 is lifted and lowered into place, when the pallet 4 and the cabinet 200 are in contact, the extension plate 511 can extend into the cabinet 200, and the left and right side edges of the cabinet 200 are correspondingly inserted into the positioning bayonet 50 so that the positions of the two are relatively fixed, so as to achieve position positioning, facilitate the trolley-type vacuum circuit breaker 100 to be accurately moved into the corresponding guide rail groove in the cabinet 200, and then facilitate the trolley-type vacuum circuit breaker 100 to smoothly enter the cabinet 200 after leaving the pallet 4 or smoothly enter the pallet 4 after leaving the cabinet 200.
[0032] The bottom plate 51 is integrally connected with the extension plate 511 on the same side to form a pad for supporting the roller 102 of the chassis 11 to move forward or backward. In addition, the pads on the left and right sides correspond to the guide grooves on the left and right sides of the cabinet 200, so that the roller 102 of the chassis 11 can enter smoothly.
[0033] Specifically, in this embodiment, the upper surface of the support plate 4 is provided with positioning columns 41 in front of the two bottom plates 51, so that when the trolley-type vacuum circuit breaker 100 is pulled onto the support plate 4, it will not be separated from the support plate 4 due to excessive force, so as to limit and position the front end of the trolley-type vacuum circuit breaker 100. The positioning column 41 is cylindrical in shape, and the top of the positioning column 41 has a hemispherical protrusion.
[0034] Furthermore, the lock hole 501 is arranged on one side of the side plate 52 close to the positioning column 41, that is, at the front position on the side plate 52; and the lock tongue 101 should be arranged at the front position on the chassis 11 to correspond to the lock hole 501. When the trolley-type vacuum circuit breaker 100 is placed in the limited accommodation space, the lock tongues 101 on the left and right sides of the chassis 11 can be inserted into the lock hole 501 to lock the chassis 11 on the pallet 4, which can effectively prevent the trolley-type vacuum circuit breaker 100 from shifting, and the handling stability is greatly improved. Among them, the shape of the lock hole 501 is rectangular, and the shape of the lock tongue 101 should match the lock hole 501, and the shape of the lock tongue 101 is also rectangular. The size of the lock hole 501 is based on the ability to insert the lock tongue 101 into the lock.
[0035] It should be noted that the assembly structure of the chassis 11 and the vacuum circuit breaker 10, the structure of the roller 102 on the chassis 11, and the structure of the lock tongue 101 on the chassis 11 are all relatively existing, and can be referred to the existing technology in actual application, and this embodiment does not make specific limitations. Moreover, the lock tongue 101 structure on the chassis 11 generally adopts an elastic reset lock tongue, and its structure for achieving elastic reset is also relatively existing, and can be referred to the existing technology in actual application, and will not be repeated in this embodiment.
[0036] Specifically, in this embodiment, the lifting mechanism 3 includes a screw rod 31 and an adjustment plate 32 that is rotatably connected to the screw rod 31 and controls the lifting of the screw rod 31; the screw rod 31 is correspondingly arranged at four diagonal positions of the relative surfaces of the support plate 4 and the frame 1. Correspondingly, a screw guide sleeve 311 for inserting the screw rod 31 is correspondingly provided on the upper surface of the frame 1; and a screw fixing sleeve 312 for inserting the screw rod 31 is correspondingly provided on the lower surface of the support plate 4.
[0037] Among them, a screw fixing sleeve 312 is installed at each of the four diagonal positions on the lower surface of the support plate 4, and then the screw 31 is inserted and tightened with a nut, so that the upper end of the screw 31 can be fixed on the support plate 4. Correspondingly, a screw guide sleeve 311 is installed at each of the four diagonal positions on the upper surface of the frame 1, and then the screw 31 is inserted, and the screw 31 can rotate therein. Correspondingly, the adjustment disk 32 is limited and rotated on the screw guide sleeve 311 and is connected with the screw 31 for rotation, so as to realize the control of the screw 31 to rise or fall through the adjustment disk 32. For example, when the adjustment disk 32 rotates clockwise in the direction of the arrow indicated in the figure, the screw 31 spirals upward, the screw 31 fixed on the support plate 4 rises, and the entire support plate 4 rises, thereby rising; on the contrary, when the adjustment disk 32 rotates counterclockwise, the screw 31 spirals down, and the entire support plate 4 falls, and the height of the support plate 4 decreases.
[0038] It should be noted that the structure for achieving lifting adjustment through the screw 31 and the adjustment disk 32 is also relatively existing. It is not described in detail in this embodiment. In actual application, any suitable existing lifting mechanism including the screw 31 and the adjustment disk 32 can be referred to to achieve lifting adjustment.
[0039] Specifically, in this embodiment, the pushing mechanism 2 includes rolling wheels 21 correspondingly arranged on the left and right sides of the frame 1, and the number of rolling wheels 21 on the same side is not less than two. Among them, the rolling wheels 21 are universal wheels. Further, the pushing mechanism 2 also includes at least two handles 22 arranged on the frame 1, and at least two handles 22 are horizontally spaced and distributed on the front side of the frame 1, so that the frame 1 is driven to move by the movement of the rolling wheels 21 on the ground during the pushing process by the handles 22, and then the lifting mechanism 3 and other components on the frame 1 are driven to move to the corresponding positions together.
[0040] By using the trolley-type vacuum circuit breaker transfer cart of the embodiment of the utility model, when transporting the trolley-type vacuum circuit breaker 100, the trolley-type vacuum circuit breaker 100 can be stably positioned on the pallet 4, effectively improving the transportation stability, and, when the pallet 4 is raised and lowered into place, the rear end of the baffle 5 is extended into the cabinet 200, and the positioning snap-in 50 at the rear end of the baffle 5 is correspondingly snapped into the left and right sides of the cabinet 200, so that the positions of the pallet 4 and the cabinet 200 are relatively fixed, which facilitates the trolley-type vacuum circuit breaker 100 to be smoothly moved into the corresponding guide rail groove in the cabinet 200 to effectively ensure the movement into place, and also facilitates the trolley-type vacuum circuit breaker 100 to be pushed out of the cabinet 200 and smoothly enter the pallet 4, so that transportation is more convenient.
[0041] It should be understood that ordinary technical workers in the field can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
