[0001] The utility model relates to the technical field of tree planting equipment, in particular to a left and right anti-dumping mechanism for a garden excavating crane. Background Art

[0002] The greening of municipal engineering is an important part of a city. With the continuous deterioration of air quality, urban greening has also attracted more and more attention. Most green plants are cultivated in the garden and grown to a certain extent, and then transplanted to the designated location by the construction workers. Therefore, corresponding equipment is needed.

[0003] For example, the "Lifting Device for Excavator" has been disclosed in the Chinese Patent Network, and the patent application number is 201720654409.4. The above device is provided with a boom on the vehicle, and a bucket is connected to the end of the boom. The bucket is connected to a lifting rope. The ground is excavated by the bucket, and the tree is tied under the bucket with the lifting rope. When the bucket is lifted, the tree is lifted.

[0004] However, the above device still has some shortcomings. When driving in gardens and green areas, the uneven ground causes the vehicle body to shake easily, and the tree itself will shake after being lifted. Therefore, when the above device lifts the tree for transportation, it is easy to cause the center of gravity to tilt, which in turn causes the vehicle body to roll over, which is easy to cause safety accidents.

[0021] The utility model is further described in detail below through the drawings and embodiments.

[0022] Embodiment 1: Figure 1-3 As shown: A left and right anti-dumping mechanism for a garden excavator crane is installed on both sides of the vehicle body. It includes a connecting frame 1, a hydraulic push rod 2, a connecting part, a support foot 4 and a motor 6. One side of the connecting frame 1 is pivoted to the vehicle body. The other side of the connecting frame 1 is welded to the drive shaft of the motor 6. The motor 6 is fixedly installed to the vehicle body. The upper end of the connecting frame 1 is hinged to the hydraulic push rod 2, and the lower end of the connecting frame 1 is connected to the support foot 4 through the connecting part. The movable end of the hydraulic push rod 2 is hinged to the upper side of the connecting part. A plurality of gripping components 5 are connected to the bottom of the support foot 4, and the gripping components 5 can extend into the soil. During operation, the hydraulic push rod 2 extends to drive the connecting part to flip, so that the support foot 4 at the lower end of the connecting part faces the ground. When the vehicle body rolls over, the support foot 4 supports the vehicle body. Prevent the vehicle body from continuing to roll over. Then the motor 6 rotates the entire connecting frame 1 to flip. Drive the support foot 4 to apply force to the ground to make the vehicle body tilt in the opposite direction to reset the vehicle body.

[0023] In the garden and greening area, a soil slope is set for aesthetics. If the vehicle body rolls over beside the soil slope, the hydraulic push rod 2 extends to push the support foot against the soil slope. However, since the soil slope itself has a slope, the support foot 4 will slide down. Therefore, a gripping component is fixedly installed on the support foot 4 to make the support foot 4 firmly grip the ground.

[0024] The grip assembly 5 includes a sleeve 51, a pin 52, a spring 53, a limit rod 54 and a connecting rod 55. The sleeve 51 is welded to the support foot 4. The pin 52 is slidably fitted in the sleeve 51, and the lower end of the pin 52 extends out from the sleeve 51. The upper end of the pin 52 is welded to the spring 53. A plurality of through grooves 511 are provided on the side wall of the sleeve 51, and the sleeve 51 is pivotally connected to a plurality of limit rods 54 using the through grooves 511. The lower end of the limit rod 54 can be flipped outward from the sleeve 51. A limit groove 541 is provided on one side of the limit rod 54. The limit rod 54 is hinged to the upper end of the connecting rod 55 through the limit groove 541. The lower end of the connecting rod 55 is hinged to the upper end of the pin 52. When the pin 52 extends into the sleeve 51, the limit rod 54 can be pushed outward. During operation, the support foot 4 is in contact with the ground. The pin 52 is inserted into the soil and extends into the sleeve 51, squeezing the spring 53. When the pin 52 extends into the sleeve 51, it drives the connecting rod 55 to rise. The connecting rod 55 pushes up the lower end of the limit rod 54, so that the lower end of the limit rod 54 is embedded in the soil.

[0025] A claw hook portion 542 is welded to the lower end of the limiting rod 54, and the claw hook portion 542 extends obliquely upward outside the sleeve 51, and the claw hook portion 542 is used to hook the soil block. The claw hook portion 542 hooks the soil block, thereby improving the gripping ability of the limiting rod 54.

[0026] The connecting part is a cross bar 3 , one end of the cross bar 3 is hinged to the supporting foot 4 , the other end of the cross bar 3 is hinged to the connecting frame 1 , and the upper surface of the cross bar 3 is hinged to the hydraulic push rod 2 .

[0027] Compared with the prior art, the left and right anti-dumping mechanism for the garden excavator crane plays a supporting role through the cooperation of the hydraulic push rod 2, the cross bar 3 and the support foot 4. When the vehicle body rolls over, it can prevent the vehicle body from continuing to tilt. Then, the pin 52, the connecting rod 55 and the limit rod 54 cooperate, and the claw hook part 542 at the lower end of the limit rod 54 is used to make the limit rod 54 embedded in the soil and firmly hook the soil block, so that the support foot 4 firmly grasps the soil slope. It is prevented that the support foot 4 slides up and down the soil slope and affects the anti-rollover of the vehicle body.

[0028] Embodiment 2: Figure 4 As shown: The basic structure of this embodiment is roughly the same as that of the first embodiment, and the following are the differences: the connecting part is an arc rod 7, the top of the arc rod 7 is arched, and a slide groove 71 is provided on the upper side of the arc rod 7, and the hydraulic push rod 2 is movably slidably fitted in the slide groove 71. One end of the arc rod 7 is hinged to the support foot 4, and the other end of the arc rod 7 is hinged to the connecting frame 1. Since the arc rod 7 is arched, it can better bear the weight of the vehicle body than the long strip. Prevent the vehicle body from being crushed when the anti-dumping mechanism is working. Further improve the load-bearing capacity of the entire mechanism.

[0029] The above-mentioned hydraulic push rod 2 is an existing ordinary hydraulic push rod. Since it is not an innovative point of this solution and no innovation is made to it, the specific model, internal structure, etc. are the same as those in the prior art and will not be described in detail.

[0030] Working principle: When in use, the hydraulic push rod 2 extends to drive the cross bar 3 to flip, so that the cross bar 3 drives the support foot 4 to descend. The support foot 4 is directed toward the ground. When the vehicle body rolls over, the support foot 4 supports the vehicle body. When the support foot 4 encounters a soil slope, the pin 52 is inserted into the soil and extends into the sleeve 51 at the same time. When the pin 52 extends into the sleeve 51, it drives the connecting rod 55 to rise. The connecting rod 55 lifts the lower end of the limit rod 54, so that the lower end of the limit rod 54 is embedded in the soil. The claw hook 542 of the limit rod 54 hooks the soil block.

[0031] In summary, the left and right anti-dumping mechanism for the garden excavator crane plays a supporting role through the cooperation of the hydraulic push rod 2, the cross bar 3 and the support foot 4. When the vehicle body rolls over, it can prevent the vehicle body from continuing to tilt. Then, the pin 52, the connecting rod 55 and the limit rod 54 cooperate, and the claw hook part 542 at the lower end of the limit rod 54 is used to make the limit rod 54 embedded in the soil and firmly hook the soil block, so that the support foot 4 can firmly grasp the soil slope. Prevent the support foot 4 from sliding up and down the soil slope and affecting the anti-rollover of the vehicle body.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
