Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example: Figure 1-4As shown, the utility model provides an arm force enhancement device for an explosion-proof loader working arm, comprising a fixed plate 1, a working arm body 2 is fixedly installed on the upper part of one side of the fixed plate 1, a first electric push rod 22 is provided on the lower part of one side of the working arm body 2, a connecting block 21 is fixedly installed on the upper part of one side of the working arm body 2, a first support rod 4 is rotatably installed in the middle part of the connecting block 21, the middle part of the first support rod 4 is rotatably installed on the driving end of the first electric push rod 22, a second electric push rod 41 is provided in the middle part of the first support rod 4, a second support rod 42 is provided in the middle part of a side of the first support rod 4 away from the second electric push rod 41, one end of the second support rod 42 is fixedly installed on the driving end of the second electric push rod 41, and a universal wheel 5 is provided at one end of the second support rod 42 away from the second electric push rod 41.

[0018] A spring 54 is fixedly installed at one end of the second support rod 42, a second fixing block 52 is fixedly installed at the end of the spring 54 away from the second support rod 42, a first fixing block 51 is fixedly installed at the end of the universal wheel 5 close to the second fixing block 52, and the first fixing block 51 and the second fixing block 52 are in contact with each other.

[0019] A first slot 221 is provided at the lower part of one side of the working arm body 2, and one end of the first electric push rod 22 is rotatably installed inside the first slot 221. By setting the first slot 221 and installing the first electric push rod 22 inside the first slot 221, the first support rod 4 can be driven by the first electric push rod 22 to fit more closely with the working arm body 2 after being folded, thereby saving more space and not affecting the normal operation of the working arm body 2 when not in use.

[0020] A second slot 421 is provided in the middle of the first support rod 4, one end of the second electric push rod 41 is fixedly installed on one side of the second slot 421, and the second support rod 42 is slidably clamped inside the second slot 421. By setting the second slot 421 and slidingly installing the second support rod 42 inside the second slot 421, the second support rod 42 slides and retracts inside the second slot 421, thereby saving more space.

[0021] A driving device 3 is rotatably installed at the lower part of one side of the fixed plate 1, and a driving end of the driving device 3 is rotatably installed at the middle part of one side of the working arm body 2. By setting the driving device 3, the working arm body 2 is driven to move through the setting of the driving device 3, so that the movement of the working arm body 2 cooperates with other parts of the loader to transport objects.

[0022] A telescopic rod 55 is fixedly installed on one side of the second support rod 42 away from the second electric push rod 41, and the telescopic end of the telescopic rod 55 is fixedly installed on the middle part of one side of the second fixed block 52. By setting the telescopic rod 55 and limiting the telescopic rod 55, when the spring 54 is buffered, the setting of the telescopic rod 55 can avoid the left and right movement of the second fixed block 52, thereby making the structure more stable.

[0023] Bolts 53 are penetrated through the middle of both sides of the second fixing block 52, and nuts 531 are threadedly installed at one end of the two bolts 53. The bolts 53 and the nuts 531 are used in conjunction with each other. By setting the bolts 53 and the nuts 531, and by threading the nuts 531 on one side of the bolts 53, the first fixing block 51 and the second fixing block 52 are fixed by the cooperation of the two, thereby facilitating the installation of the universal wheel 5 at one end of the second support rod 42.

[0024] Both ends of the first fixing block 51 and the second fixing block 52 are provided with symmetrically distributed mounting holes 532. By providing the mounting holes 532, the first fixing block 51 and the second fixing block 52 can be conveniently fixed by passing the bolts 53 through the mounting holes 532, thereby limiting the position of the universal wheel 5.

[0025] Working principle: In actual use, the driving device 3 can drive the working arm body 2 to move up and down. When the driving device 3 drives the working arm body 2 to rise, the first electric push rod 22 can be started, and the folded first support rod 4 can be unfolded outward under the push of the first electric push rod 22 until it is 90 degrees with the ground, and the second support rod 42 can be driven downward by the drive of the second electric push rod 41, so that the universal wheel 5 can contact the ground. The vertical support force can be applied to the working arm body 2 by the drive of the first electric push rod 22 and the second electric push rod 41, so that the arm strength of the working arm body 2 is strengthened;

[0026] By arranging a spring 54 between the universal wheel 5 and the second support rod 42 , the spring 54 is used to buffer the second support rod 42 under the reaction force, so that the universal wheel 5 is more stable when moving.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
