According to the rapid lifting mechanism for the support legs of the welding trolley, the arrangement of the pedal frame and the supporting component enables an operator to adjust the height of the support legs without squatting down and twisting by hands, and the support legs can be adjusted only by using the pedal frame, so that the chassis and the upper trolley body can be stably supported, and the rapid lifting mechanism is more convenient and rapid to operate. Meanwhile, due to the arrangement of the reset assembly, an operator can realize the reset function of the support legs in a pedal reset pedal mode, so that the operator can conveniently switch the working modes of the welding trolley.
The concrete principle and the working engineering of the rapid lifting mechanism of the support leg of the welding tractor are as follows.
In the initial state, the central articulated shaft 15 connecting the driving arm and the linkage arm is positioned at a low point, and the linkage arm and the pedal frame are positioned at a basically horizontal position. When the supporting legs need to be supported, an operator can step on the front end of the pedal frame by feet. The driving arm is fixedly connected with the pedal frame, the end part of the driving arm is hinged on the mounting frame through the first hinge shaft, and the driving arm and the pedal frame form a lever taking the first hinge shaft as a rotating shaft. When the operator steps on the end of the frame, the end descends to drive the other end of the driving arm and the central hinge shaft to ascend. Along with the rising of the central articulated shaft, the end part of the linkage arm hinged on the central articulated shaft also rises along with the rising of the central articulated shaft. The linkage arm is also a lever taking the second articulated shaft as a rotating shaft, after the end part of the linkage arm connected with the central articulated shaft rises, the lifting shaft with the other end hinged with the end part of the linkage arm begins to descend, and then the support legs positioned at the bottom end of the lifting shaft are driven to descend.
After the bottom ends of the support legs are contacted with the ground, the central driving shaft continues to ascend under the driving of the pedal frame until the central driving shaft ascends to the highest point. The feet are now in full contact with the ground while the rollers on the chassis are disengaged from the ground.
When the pedal frame rotates by the first hinge shaft, the reset connecting plate with one end hinged on the pedal frame descends under the driving of the pedal frame. Along with the movement of the end part of the reset connecting plate, the reset connecting plate and the reset pedal are hinged to form the connecting plate component which is in an inverted V-shaped structure in an initial state, gradually rotates around a hinge shaft in the middle of the reset pedal to pass through a dead point and form a self-locking positive V-shaped structure, so that the functions of descending driving of the supporting legs and locking of a vehicle body are completed.
The stop point is the position where the reset pedal is basically flush with the reset connecting plate, and at the moment, the thrust of the pedal frame to the reset connecting plate and the reset pedal passes through a hinge shaft of the reset pedal, the moment formed by the hinge shaft is minimum, and the reset connecting plate and the reset pedal are difficult to drive to rotate. Meanwhile, the second hinged shaft is close to one end of the linkage arm connected with the lifting shaft, the first hinged shaft is close to one end of the driving arm connected with the central hinged shaft, the thrust of the ground to the reset connecting plate after passing through a lever group formed by the linkage arm and the driving arm is reduced, the ground cannot drive the reset connecting plate and the reset pedal to automatically cross a stop point to reset the supporting legs, and therefore the locking function is achieved, and on the contrary, the purpose of supporting the supporting legs can be achieved through small treading force of an operator. In addition, a locking spring can be arranged between the reset pedal and the reset connecting plate to provide certain pretightening force.
In order to reset the supporting leg, an operator can drive the reset connecting plate and the reset pedal to reversely cross a dead point in a mode of trampling the reset pedal, and drives the supporting leg to ascend according to the reverse process, so that the resetting of the supporting leg is realized.
From the above description, it can be seen that, in order to prop up the vehicle body, the operator can easily drive the support legs to descend by stepping on the pedal frame to prop up the chassis and the vehicle body, and meanwhile, the operator can reset the support legs by stepping on the reset pedal.
Wherein the chassis comprises a connecting plate 16 connecting the two sets of support assemblies, and the vehicle body can be directly arranged on the connecting plate. The middle part of the reset pedal is hinged on a hinge seat on the connecting plate.
In this embodiment, the mounting bracket is U type mounting bracket, and it includes two square pipes and connects the bottom plate of two square pipes. The gyro wheel passes through the gyro wheel support and sets up in the mounting bracket both ends. The lifting shaft may be disposed within a sliding sleeve 17 on the base plate.
The both ends of linkage arm can set up to waist hole to the rotation of adaptation linkage arm around the second articulated shaft also can set up its tip into the change of length when the telescopic link is in order to adapt to it to rotate in addition, and this telescopic link can be air spring or mechanical type spring telescopic link, and its concrete structure and principle are conventional technology, and no longer the repeated description here. In this embodiment, one end of the linkage arm is provided with a waist hole, and the other end is a telescopic rod.
The driving arm is U-shaped steel, a side plate of the driving arm is fixedly connected with the pedal frame through a bolt, one end of the side plate is provided with a notch 18 adaptive to the central articulated shaft, and the other end of the side plate is connected with a second articulated shaft. When the linkage arm works, the driving arm drives the end parts of the central articulated shaft and the linkage arm to lift through the notch.
Can set up mounting groove 19 on the lateral wall of mounting bracket, be provided with U type locating rack 20 between two square pipes, U type locating rack includes base plate 25, be connected with two baffle 21 of locating in the mounting groove respectively on the base plate, the baffle surface sets up the guide slot 22 with central articulated shaft tip adaptation, the both ends of central articulated shaft set up respectively in the guide slot of both sides, in order to realize the guide function to central articulated shaft, it is more stable also to make its lift simultaneously, in addition also play the limit function to central articulated shaft.
In this embodiment, the two sides of the central hinge shaft are provided with the linkage arms to realize the lifting driving of the support legs at the two ends of the mounting frame.
The pedal frame comprises a U-shaped frame 23 and a crank arm 24 fixedly connected with the U-shaped frame, and two ends of the crank arm are respectively fixedly arranged at one end of the driving arm close to the first hinged shaft. The end part of the reset pedal is hinged in the middle of the U-shaped frame.
