Description

A kind of push-pull mechanism

Technical field

A kind of push-pull mechanism, belongs to sanitation equipment technical field, more particularly in the supporting transfer car(buggy) of refuse compaction equipment For compartment removable garbage truck when support the use when, realize compartment with the docking of compressor or detached push unit.

Background technology

When the supporting transfer car(buggy) of refuse compaction equipment is compartment removable garbage truck, translation compartment is needed to be allowed to and compressor pair Connect or separate, i.e.,：Press-fit position by putting case position and moving to（Compressor front）Realize that punch-out equipment is docked, or vanning is moved to by position is press-fited Position（Torque arm car is facilitated to case）Realize that punch-out equipment is separated, it is general at present that longitudinal-moving device is arranged in into compression device below, due to compression The following installing space of equipment is less, it is impossible to realize vertically moving rubbish compartment long range, install bad adaptability, can fall on Rubbish and percolate, it is not easy to clear up, cause secondary pollution.

Utility model content

Technical problem to be solved in the utility model be to provide it is a kind of rubbish compartment can over long distances be vertically moved push away Drawing mechanism.

To solve above-mentioned technical problem, the technical scheme that the utility model is adopted：A kind of push-pull mechanism, including drag hook, Push away hook, push rod, fixed block and guide plate, it is described to push away that hook one end is hinged with drag hook end, the other end and push rod end are hinged, in institute State and push away the side of hook and drag hook hinged place and be provided with the fixed block for vertically standing in ground, the generally inverted L-shaped of the guide plate, and And guide plate upper end is hinged with fixed block top, lower end is arc free end, and the guide part of the arc free end is with drag hook With circular arc of the pin joint for the center of circle for pushing away hook；

It is provided with to limit on the drag hook and pushes away the upper limit position block that hook rotates upper limit, be provided with hook and drag hook end in described pushing away Portion inclined-plane coordinates and limits and push away the lower position block that hook rotates lower limit, and the side of guide plate is provided with rolling above hook in described pushing away Wheel；

The first U-type groove for allowing roller to pass through, bottom are provided with the top of the fixed block be provided with the 2nd U that allows roller to pass through Type groove, one end being hinged in the guide plate and fixed block is provided with the 3rd U-type groove for allowing roller to pass through, and the 3rd U-type groove with The position of the first U-type groove is concordant.

The push rod is cylinder piston rod.

The hook that pushes away is hinged by connecting shaft with drag hook, and the guide plate is hinged by rotating shaft with fixed block.

Compared to the prior art the utility model has the advantages that.

First, when rubbish compartment prepares to be docked with compression device, first rubbish compartment is positioned on drag hook, this practicality is new Type pushes away hook and rotates around connecting shaft by push rod, pushes away the roller on hook while transporting upwards along the cambered surface free end of guide plate It is dynamic, it is rotated up when to push away stop after hook encounters upper limit plate, now roller can just pass through the 3rd U-type groove of guide plate, push away Bar is continued to press on and pushes away hook so that drag hook, is pushed away hook and is started to travel forward, roller also gradually along the 3rd U-type groove, fixed block first U-type groove travels forward, until drag hook proceeds to specified location；

When rubbish compartment prepares to be separated with compression device, the utility model is pulled by push rod and pushes away hook around connecting shaft turn It is dynamic, until pushing away the lower limiting board of hook and being hinged after end contact for drag hook, push away hook and stop operating, now push away hook in horizontal State, push rod is pulled on and pushes away hook so that drag hook, is pushed away hook and is started to move backward, pushes away the 2nd U of the roller of hook along fixed block bottom When type groove passes through, the arc free end of guide plate, until roller exceedes after guide plate, is fallen back to just by roller jack-up under guide plate Beginning position, wait working cycles next time；

Thus, the utility model is achieved that the length in rubbish compartment by push rod, the cooperation for pushing away hook, drag hook and guide plate Distance is vertically moved, and the course of work is simple, convenient, at the same the utility model take up room it is little, it is adaptable to the little field of installing space Close.

2nd, the U that the first U-type groove, the second U-type groove, the 3rd U-type groove are disposed as facilitating roller to pass through by the utility model Type so that roller follows and pushes away hook and release or when retracting, steadily quickly can pass through from U-type groove, it should be noted that roller By not contacting with U-type groove during U-type groove；

While the purpose that the free end for being directed to plate is set to arc is：When push rod pushes away hook, roller is along guide plate Cambered surface motion can avoid pushing away hook cannot normally along connecting shaft rotation, and drag hook may not also be turned at upper limit plate just hook is pushed away Travel forward in advance, rear roller just cannot be normal through U-type groove.

Specific embodiment

As shown in Fig. 1-Fig. 7, a kind of push-pull mechanism, including drag hook 1, push away hook 2, push rod 4, fixed block 7 and guide plate 8, institute State and push away that the one end of hook 2 is hinged with the end of drag hook 1, the other end and the end of push rod 4 are hinged, described the one of hook 2 and the hinged place of drag hook 1 is pushed away Side is provided with the fixed block 7 for vertically standing in ground, the generally inverted L-shaped of the guide plate 8, and the upper end of guide plate 8 and fixation The top of block 7 is hinged, and lower end is arc free end, and the guide part of the arc free end is to be with the pin joint for pushing away hook 2 with drag hook 1 The circular arc in the center of circle；

It is provided with to limit on the drag hook 1 and pushes away the upper limit position block 5 that hook 2 rotates upper limit, is provided with hook 2 and drawing in described pushing away The end chamfer of hook 1 coordinates and limits and push away the lower position block 6 that hook 2 rotates lower limit, pushes away above hook 2 to the one of guide plate 8 described Side is provided with roller 10；

Being provided with the first U-type groove 11, bottom for allowing roller 10 to pass through and be provided with the top of the fixed block 7 allows roller 10 to pass through The second U-type groove 12, the one end being hinged in the guide plate 8 and fixed block 7 is provided with the 3rd U-type groove 13 for allowing roller 10 to pass through, And the 3rd U-type groove 13 is concordant with the position of the first U-type groove 11.

The push rod 4 is cylinder piston rod.

The hook 2 that pushes away is hinged by connecting shaft 3 with drag hook 1, and the guide plate 8 is hinged by rotating shaft 9 with fixed block 7.

The push rod 4 can also be cylinder, electric pushrod or other by mechanism's band except being cylinder piston rod The type of drive such as dynamic connecting rod.

The rotating shaft 9 and the gap for having very little with the hinge hole of fixed block 7, after guide plate 8 falls in place, guide plate 8 With the end face of fixed block 7 be in close contact, it is ensured that when roller 10 move backward encounter the arc free end of guide plate 8, travel forward along When the arc free end of guide plate 8 rolls, rotating shaft 9 is not hit power and extruding force.

Above-described embodiment is unrestricted to the explanation of the utility model structure, without departing from the utility model principle premise Lower made deformation is also within protection domain of the present utility model.For example the first U-type groove 11 is designed as into other convenient for rolling The shape that wheel 10 is oriented to.
