As shown in fig. 1-8, the crank arm type aerial work platform electric cabinet comprises an electric cabinet 2 fixed on an aerial work platform 1 and with an upward cabinet opening, wherein a cabinet cover 3 is hinged at the cabinet opening of the electric cabinet 2, and a window opening capable of being watched inside the electric cabinet 2 is arranged on the cabinet cover 3; an elastic piece for blocking the closing of the box cover 3 is arranged between the electric control box 2 and the box cover 3, and a limiting component for keeping the box cover 3 closed is also arranged between the electric control box 2 and the box cover 3.

It should be noted that the conventional crank arm type aerial platform 1 is generally composed of a rectangular platform chassis and a metal fence frame disposed around the top thereof, and the controller for controlling the aerial platform 1 is generally disposed on the side of the top of the fence frame near the crank arm. Therefore, the position of the electric cabinet 2 in actual installation is consistent with the installation position of the conventional operation platform controller, and the controller for controlling the operation of the aerial operation platform 1 is installed in the electric cabinet 2.

In this embodiment, a fixing seat 11 is provided on the fence frame of the aerial work platform 1, the fixing seat 11 is angle iron, angle code, etc., and the fixing seat 11 is connected to the fence frame of the aerial work platform 1 by bolts or welding and is used for fixing the electric cabinet 2.

As a specific embodiment, hinge seats (not shown in the figure) are respectively and correspondingly arranged on the electric cabinet 2 and the box cover 3, and the corresponding two hinge seats are hinged through a pin shaft.

In this embodiment, as shown in fig. 2, the viewing window provided on the case cover 3 is composed of a through hole formed in the case cover 3 and a transparent plate 21 fitted on the through hole. Preferably, the through opening and the transparent plate 21 occupy the top surface part and the front side surface part of the box cover 3 as much as possible, so that operators can more clearly see the real-time state of each controller arranged inside the electric cabinet 2; the transparent plate 21 is preferably made of an acrylic transparent material, namely, the transparent plate has good light transmittance and high toughness, and is suitable for construction site operation.

As a specific embodiment, as shown in fig. 5 and fig. 7, the rear sides of the case cover 3 and the electric cabinet 2 are respectively provided with a second ear plate 33 and a first ear plate 23, and the elastic member is a tension spring 5 connected between the second ear plate 33 and the first ear plate 23, and the tension spring 5 is always stressed. Through extension spring 5, can make case lid 3 not receive under the effect of other external forces, keep case lid 3 to open, can not lead to the fact case lid 3 to close because of adjusting crank arm type operation car walking or lift operation platform etc. the controller that the operation of assurance operating personnel safety, stability is located electric cabinet 2 inside.

As a specific embodiment, as shown in fig. 3, 5 and 8, the limiting assembly includes a lock body 41 fixed on the front side of the electric cabinet 2, a lock pin 42 capable of penetrating out of the lock body 41 is slidably disposed in the lock body 41 left and right, a spring 43 for preventing the lock pin 42 from completely entering the lock body 41 is further disposed between the lock body 41 and the lock pin 42, an oblique angle portion 421 is disposed at one end of the lock pin 42 penetrating out of the lock body 41, an oblique surface of the oblique angle portion 421 is gradually inclined from a front end close to the lock body 41 to a rear end far away from the lock body 41, and a lock plate 34 vertically corresponding to the oblique angle portion 421 of the lock pin 42 is disposed on the case cover 3. It should be noted that there is a gap between the lock pin 42 and the electric cabinet 2, the width of which is slightly larger than the thickness of the lock plate 34, and the lock plate 34 is located in the gap between the lock pin 42 and the electric cabinet 2 when the cover 3 is closed. Thus, when the case cover 3 is closed from the open state to the closed state, the case cover 3 is driven to be closed, the process lock plate 34 interferes with the bevel portion 421 of the lock pin 42, the bevel portion 421 receives a pushing force of the lock plate 34, the force received by the bevel portion 421 forms a component force for driving the lock pin 42 to move towards the inside of the lock body 41 by the bevel surface, therefore, the process lock pin 42 is retracted into the lock body 41, the spring 43 is stressed to be contracted until the case cover 3 is completely closed, the lock plate 34 is separated from the bevel portion 421 of the lock pin 42, the interference disappears, the bevel portion 421 of the lock pin 42 is extended out of the lock body 41 again under the elastic force of the spring 43, and the rear side surface of the bevel portion 421 forms a limit to the lock plate 34, thereby closing and locking of the case cover 3 are completed.

Specifically, in the present embodiment, the rear side of the lock body 41 is provided with the connection portion 412, and the connection portion 412 is fixed to the front side of the electric cabinet 2 by a screw, so that the lock body 41 is fixed to the electric cabinet 2.

Further, in order to facilitate opening of the cover, the lock pin 42 is provided with an adjusting knob 44 protruding from the front side of the lock body 41. As a specific embodiment, as shown in fig. 8, a slide way (not shown in the drawing) penetrating from left to right is provided in the lock body 41, the lock pin 42 is slidably disposed in the slide way, a slide hole 411 communicating with the slide way is provided on the front side surface of the lock body 41, one end of the slide hole 411 is a blind end, the other end is an open end, when the lock pin 42 is inserted into the slide way, the slide way is inserted into the slide hole 411 from one side of the slide way near the open end of the slide hole 411, the adjusting button 44 enters the slide hole 411 from one side of the open end of the slide hole 411, then the spring 43 is inserted into the slide way, the insertion end of the spring 43 is the same as the insertion end of the adjusting button 44, and finally the spring 43 is limited in the slide way by adopting the cover plate 45. In this way, under the action of the elastic force of the spring 43, the bevel portion 421 of the lock pin extends out of the lock body 41, meanwhile, the blind end of the sliding hole 411 interferes with the adjusting knob 44 to prevent the lock pin 42 from being completely separated from the slideway, the bevel portion 421 of the lock pin can enter the slideway by moving the adjusting knob 44, the limit of the lock plate 34 is released, and the box cover 3 is quickly opened under the action of the tension spring 5.

Further, as shown in fig. 5 and 6, a stop lever 21 extending upward and rearward is provided at the rear side of the electric cabinet 2, a first shock pad 22 is provided at the free end of the stop lever 21, and a second shock pad 32 corresponding to the first shock pad 22 is provided at the rear side of the cabinet cover 3. The purpose of this design is that the maximum rear angle of the case cover 3 when opened can be limited by the limit rod 21, preferably, the maximum rear angle of the case cover 3 when opened is set at 135-150 degrees, so that the case cover 3 can not be turned backwards too much while the operator is ensured not to operate the controller in the electric cabinet 2, and the case cover 3 can be closed again conveniently. Meanwhile, the first and second shock-absorbing pads 22 and 32 can reduce the magnitude of the response collision and vibration occurring when the cover 3 is in contact with the stopper rod 21 when opened.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
