Description

Technical Field

[0001] The utility model relates to a modular pull-out pedal and belongs to the technical field of engineering machinery. Background Art

[0002] Construction machinery is widely used in construction projects such as housing construction, high-speed rail construction, and bridge construction. Currently, excavators and pile-driving machinery mostly use excavator chassis. During the construction process, the operator needs to enter and exit the cab, assist the driver outside the cab, move around daily, and repair equipment. Therefore, it is necessary to set pedals on the outside of the cab and on the vehicle platform. In the prior art, pedals are mostly fixed or flip-up. Both methods have the disadvantages of occupying a large space and being inconvenient to disassemble and assemble, which will increase the risk of walking collisions and transportation costs. Utility Model Content

[0003] The utility model provides a modular pull-out pedal for overcoming the defects of the prior art excavator pedal that the pedal occupies a large space, is inconvenient to assemble and disassemble, and increases the risk of collision during walking.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] The utility model discloses a modular pull-out pedal, comprising a pedal, wherein sliding grooves are provided on both sides of the pedal, and slideways are provided on a left mounting seat and a right mounting seat, and pins are provided at the connection between the two and the pedal, and the slideways and the sliding grooves are limited by the pins, and a sliding connection is realized so that the left mounting seat and the right mounting seat can be telescoped in the pedal.

[0006] Furthermore, the guardrail is installed by plugging with the pedal through a sleeve arranged behind the pedal and fastened with bolts.

[0007] Furthermore, a cotter pin is provided on the pin shaft to prevent it from lateral movement.

[0008] Furthermore, the slide groove is horizontal in the middle, and both ends are tilted upwards.

[0009] Furthermore, the slideway is horizontal at the inner end and the middle part, and sunken at the outer end.

[0010] The beneficial effects achieved by the utility model are as follows: the pedal body is made of aluminum alloy material to ensure strength and reduce weight, it is more labor-saving than a flip-up pedal, has a simple and compact structure, occupies little space, can be stored under the chassis when not in use, and can be quickly pulled out and unfolded when in use, has low cost, good versatility, and can be modularly used as a fully enclosed pedal and guardrail for getting on the vehicle; it is protected by the vehicle frame to prevent collision and will not affect the cab switch, and is equipped with a locking mechanism to ensure that the pedal is stably fixed in the fully unfolded and retracted states.

[0016] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0017] Example 1

[0018] like Figure 1-3 As shown, a modular pull-out pedal includes a pedal 3, wherein sliding grooves are provided on both sides of the pedal 3, and slideways are provided on the left mounting seat 1 and the right mounting seat 6. Pin shafts 2 are provided at the connection between the two and the pedal 3, and the slideways and the sliding grooves are limited by the pin shaft 2, and the sliding connection of the left mounting seat 1 and the right mounting seat 6 to be telescopic in the pedal 3 is realized.

[0019] The guardrail 4 is plugged and installed with the pedal 3 through a sleeve arranged behind the pedal 3 and is fastened with bolts 5.

[0020] The pin shaft 2 is provided with a cotter pin to prevent it from lateral movement.

[0021] The slide groove is horizontal in the middle, and both ends are tilted upwards.

[0022] The slideway is horizontal at the inner end and the middle part, and is sunken at the outer end.

[0023] The left mounting seat 1 and the right mounting seat 6 are welded below the chassis of the excavator.

[0024] When the pedal 3 needs to be pulled out, the pedal 3 is lightly lifted and pulled outward, and the pin shaft 2 is stuck at the upwardly tilted end on the left side of the pedal 3, and the pedal 3 can be locked by its own weight.

[0025] When the pedal 3 needs to be retracted, the pedal 3 is lightly lifted and pushed inwards, the pin 2 is clamped at the upwardly raised end on the right side of the pedal 3, and the pin 2 is clamped at the sunken outer end of the slideway by the pedal 3's own weight to lock it.

[0026] The pedal body is made of aluminum alloy to ensure strength and reduce weight. It is more labor-saving than flip-up pedals, has a simple and compact structure, occupies little space, can be stored under the chassis when not in use, and can be quickly pulled out and unfolded when in use. It has low cost and good versatility, and can be modularly used as a fully enclosed pedal and guardrail for getting on the vehicle. It is protected by the vehicle frame to prevent collision and will not affect the cab switches. It is equipped with a locking mechanism to ensure that the pedal is stably fixed in the fully extended and retracted states.
