Description

Technical Field

[0001] This application relates to the field of special vehicle operation equipment technology, and in particular to an insulated vehicle for high-altitude operations. Background Technology

[0002] Aerial work platforms are special vehicles used for the installation, maintenance, and cleaning of high-altitude equipment. Compared with traditional methods such as scaffolding and ladders, they have advantages such as better performance, higher efficiency, and greater safety.

[0003] For example, Chinese Patent Application No. 202322605118.4 discloses a hybrid boom aerial work platform, including a vehicle body. A box is fixedly mounted on the outer wall of the vehicle body. A rotating platform is rotatably connected to the top of the box. A rotating base is fixedly mounted on the top of the rotating platform. A first drive cylinder is rotatably connected to the outer wall of the rotating base. A first support arm is rotatably connected to the outer wall of the first support arm. A second drive cylinder is rotatably connected to the outer wall of the first support arm. A third drive cylinder is installed on the outer wall of the second support arm. A basket is rotatably connected to the outer wall of the second support arm. A pressure switch is fixedly mounted at the bottom of the inner cavity of the basket. A support assembly is fixedly mounted at the bottom of the inner cavity of the basket. A load-bearing platform is fixedly mounted on the top of the support assembly. A protective plate is rotatably connected to the inner wall of the basket. A fixing column is fixedly mounted on the outer wall of the protective plate.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] When a typical aerial work platform insulated vehicle is not in operation and is driving normally on the road, the work bucket is usually suspended in the air or simply placed on the vehicle chassis. When the vehicle is driving on rough road conditions, the work bucket will experience significant vibrations. These vibrations can cause great damage to the connection mechanism between the work bucket and the telescopic boom. Subsequently, the work bucket is likely to loosen or shake during aerial work, posing a significant safety hazard. Utility Model Content

[0006] This application provides an insulated vehicle for high-altitude operations to improve the following technical problems:

[0007] Common work buckets are usually suspended in the air or simply placed on the vehicle chassis. When the vehicle is traveling on rough roads, the work bucket will experience significant vibrations. These vibrations can cause great damage to the connection mechanism between the work bucket and the telescopic boom. Subsequently, the work bucket is likely to loosen or shake during high-altitude operations, posing a significant safety hazard.

[0008] This application provides an insulated vehicle for high-altitude operations, which adopts the following technical solution:

[0009] An insulated aerial work platform includes a vehicle chassis, a folding telescopic boom, and a work bucket. The bottom of the folding telescopic boom is fixed to the middle of the vehicle chassis, and the work bucket is connected to the bottom of the folding telescopic boom. A support platform is provided at the rear of the vehicle chassis. When the folding telescopic boom is in the retracted state, the work bucket rests on the support platform. An elastic base is movably connected to the middle of the upper surface of the support platform, and a snap-fit ​​base is movably connected to the middle of the bottom surface of the work bucket. The snap-fit ​​base is used to snap and fix the work bucket to the elastic base to reduce the vibration caused by the vehicle's movement.

[0010] In one feasible technical solution of this application, the elastic base includes a first hinge seat, a first hinge arm and two sets of elastic support parts. The middle part of the first hinge arm is hinged to the first hinge seat, the first hinge seat is fixed to the upper surface of the support platform, and the two sets of elastic support parts are respectively fixed to both ends of the upper surface of the first hinge arm.

[0011] In one feasible technical solution of this application, the first hinge seat is a U-shaped card seat welded from stainless steel plate, the middle part of the first hinge arm is located in the card slot of the U-shaped card seat and is hinged through the first rotating shaft, and the first hinge arm is a square steel tube or channel steel.

[0012] In one feasible technical solution of this application, the elastic support includes a strip tray and a rubber cylinder. The strip tray and the rubber cylinder have the same length. The upper surface of the end of the first hinge arm is vertically connected to the bottom surface of the middle part of the strip tray. The rubber cylinder is placed inside the strip tray and the two are fixedly connected.

[0013] In one feasible technical solution of this application, the bottom of the rubber cylinder and the end of the strip tray are connected and fixed by a number of sets of bolts.

[0014] In one feasible technical solution of this application, the length of the rubber cylinder and the first hinge arm is between 25 and 40 cm, and the diameter of the rubber cylinder is between 8 and 15 cm.

[0015] In one feasible technical solution of this application, the snap-fit ​​base includes a second hinge seat, a second hinge arm, and a U-shaped slot plate. The middle part of the second hinge arm is hinged to the second hinge seat, the second hinge seat is fixed to the lower surface of the working bucket, and the opening of the U-shaped slot plate is arranged downward and the top is fixed to the lower surface of the first hinge arm.

[0016] In one feasible technical solution of this application, the bottom two sides of the U-shaped slot plate are provided with guide inclined plates that are inclined outward, and the two guide inclined plates form a flared structure.

[0017] In one feasible technical solution of this application, the U-shaped card slot plate is further provided with an elastic protective member inside, which is used to prevent the card base from excessively squeezing the elastic base.

[0018] In one feasible technical solution of this application, the elastic protective component includes a fixed cylinder and a protective spring. The fixed cylinder is welded and fixed to the middle of the groove bottom of the U-shaped slot plate, and the top of the protective spring is welded and fixed inside the fixed cylinder. The minimum length of the protective spring under extreme compression is equal to the depth of the U-shaped slot plate.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] As the work bucket gradually approaches and rests on the support platform, the locking base will gradually lock onto the elastic base. Through the initial locking and elastic connection between the locking base and the elastic base, the work bucket is effectively prevented from shaking significantly from side to side and up and down relative to the support platform. Therefore, even if the vehicle is traveling on a rough road, it will not cause significant shaking to the work bucket. This provides good protection for the connection mechanism between the work bucket and the folding telescopic arm. The work bucket is less likely to loosen or shake during subsequent high-altitude operations, indirectly reducing safety hazards. Attached Figure Description

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses an insulated vehicle for high-altitude operations. (Refer to...) Figure 1-3The high-altitude work insulated vehicle includes a vehicle chassis 1, a folding telescopic boom 2, and a work bucket 3. The bottom of the folding telescopic boom 2 is fixed to the middle of the vehicle chassis 1, and the work bucket 3 is connected to the bottom of the folding telescopic boom 2. A support platform 4 is provided at the rear of the vehicle chassis 1. When the folding telescopic boom 2 is in the retracted state, the work bucket 3 rests on the support platform 4. An elastic base 5 is movably connected to the middle of the upper surface of the support platform 4, and a snap-fit ​​base 6 is movably connected to the middle of the bottom surface of the work bucket 3. The snap-fit ​​base 6 is used to snap and fix the work bucket 3 to the elastic base 5 to reduce the vibration caused by the vehicle's movement.

[0038] In this embodiment, the elastic base 5 includes a first hinge seat 51, a first hinge arm 52, and two sets of elastic support parts. The middle part of the first hinge arm 52 is hinged to the first hinge seat 51. The first hinge seat 51 is fixed to the upper surface of the support platform 4. The two sets of elastic support parts are respectively fixed to the two ends of the upper surface of the first hinge arm 52. The first hinge seat 51 is a U-shaped card seat welded from stainless steel plate. The middle part of the first hinge arm 52 is located in the card slot of the U-shaped card seat and is hinged through the first rotating shaft 6653. The first hinge arm 52 is a square steel tube or channel steel. The elastic support includes a strip tray 54 and a rubber cylinder 55. The strip tray 54 and the rubber cylinder 55 have the same length. The upper surface of the end of the first hinge arm 52 is vertically connected to the bottom surface of the middle part of the strip tray 54. The rubber cylinder 55 is placed inside the strip tray 54 and the two are fixedly connected. The bottom of the rubber cylinder 55 and the end of the strip tray 54 are connected and fixed by several sets of bolts 56. The length of the rubber cylinder 55 and the first hinge arm 52 is between 25-40 cm, and the diameter of the rubber cylinder 55 is between 8-15 cm.

[0039] The elastic base 5 designed above has a simple structure and is firmly installed. Since the first hinge arm 52 is a movable hinge structure, the entire elastic base 5 can swing to a certain extent with the shaking of the vehicle. In addition, with the elastic support of the rubber cylinder 55, it can not only ensure the connection stability of the work bucket 3, but also reduce the shaking amplitude of the vehicle to the work bucket 3, resulting in better stability.

[0040] In this embodiment, the snap-fit ​​base 6 includes a second hinge seat 61, a second hinge arm 62, and a U-shaped snap-fit ​​plate 63. The middle part of the second hinge arm 62 is hinged to the second hinge seat 61, and the second hinge seat 61 is fixed to the lower surface of the working bucket 3. The opening of the U-shaped snap-fit ​​plate 63 is arranged downward and the top is fixed to the lower surface of the first hinge arm 52. The bottom two sides of the U-shaped snap-fit ​​plate 63 are provided with guide inclined plates 631 that are inclined outward. The two guide inclined plates 631 form a flared structure. The U-shaped snap-fit ​​plate 63 is also provided with an elastic protective component. The elastic protective component is used to prevent the snap-fit ​​base 6 from excessively compressing the elastic base 5. The elastic protective component includes a fixed cylinder 64 and a protective spring 65. The fixed cylinder 64 is welded and fixed to the middle of the bottom of the U-shaped snap-fit ​​plate 63. The top of the protective spring 65 is welded and fixed inside the fixed cylinder 64. The minimum length of the protective spring 65 under the extreme compression state is equal to the depth of the U-shaped snap-fit ​​plate 63.

[0041] The second hinge seat 61 is also a U-shaped seat welded from stainless steel plate. The middle part of the second hinge arm 62 is located in the slot of the U-shaped seat and is hinged through the second pivot. The second hinge arm 62 is a square steel tube or channel steel.

[0042] The snap-fit ​​base 6 designed above has a simple structure and is firmly installed. Since the second hinge arm 62 is a movable hinge structure, the entire snap-fit ​​base 6 can swing to a certain extent with the shaking of the work bucket 3. In addition, with the elastic support of the rubber cylinder 55, it can not only ensure the connection stability of the work bucket 3, but also the design of the protective spring 65 can prevent the U-shaped slot plate 63 from rigidly contacting the elastic base 5 or even the support platform 4 under extreme road conditions, thus providing good protection for the U-shaped slot plate 63.

[0043] The beneficial technical effects of the high-altitude work insulated vehicle according to the embodiments of this application are roughly as follows:

[0044] As the work bucket 3 gradually approaches and rests on the support platform 4, the locking base 6 gradually locks onto the elastic base 5. Through the initial locking and elastic connection between the locking base 6 and the elastic base 5, a good buffering effect is achieved, effectively preventing the work bucket 3 from shaking significantly from side to side and up and down relative to the support platform 4. Therefore, even if the vehicle is driving on a rough road, it will not cause significant shaking to the work bucket 3. It also provides good protection for the connection mechanism between the work bucket 3 and the folding telescopic arm 2. During subsequent high-altitude operations, the work bucket 3 is less likely to loosen or shake, indirectly reducing safety hazards.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
