Description

Technical Field

[0001] The invention discloses a large mass load connecting device with an auxiliary lifting mechanism, which relates to a device used for relaying and transporting equipment with a relatively large mass. Background Art

[0002] In modern production and life, there are many large-sized and heavy equipment that need to be transported from vehicles over short distances. In the past, they were mostly transported manually by multiple people, or by forklifts and shovels. In particular, in the maintenance of power lines, crawler-type insulated boom trucks are needed. However, the existing crawler-type insulated boom trucks are crawler-type walking devices and are not suitable for long-distance travel alone. Trucks are currently used for transportation. Due to the height difference between the crawler-type insulated boom truck and the truck compartment, it is very inconvenient for the crawler-type insulated boom truck to get on and off the truck. It is also specifically manifested as (1) crawler-type insulated boom trucks (1) It takes two crane shifts to transport the insulated boom truck to the work site; (2) There is a safety risk that the crawler insulated boom truck will be damaged during the lifting process; (3) Due to site restrictions, the crane and flatbed truck may not be able to work together to lift the crawler insulated boom truck; (4) Multiple staff members are required to cooperate on site, which is time-consuming and labor-intensive, reduces work efficiency, increases operating costs, and is not conducive to cost savings; and relying on the rear launch plate of a conventional trailer for loading and unloading has the following problems: When the loading and unloading process passes through the junction of the launch plate and the truck cargo box, the impact force of the fall will damage the mechanical structure of the crawler.

[0003] At the same time, when using manual transportation of goods, due to the large size and weight of these equipment, it is difficult to gather a large number of people in many occasions, and the porters may also be injured due to carrying heavy objects; when using forklifts or shovel trucks for transportation, since the forklifts or shovel trucks need to be temporarily inserted into the bottom of the goods, if too much force is used during insertion, the bottom of the goods is easily damaged; therefore, it is necessary to provide a device that is placed on the device before transportation, and after being transported to the final location by truck, the self-loading and unloading characteristics of the device can automatically transport the goods to the predetermined location without additional loading and unloading. Summary of the invention

[0004] In view of this, the present invention provides a large-mass load docking device with an auxiliary lifting mechanism. Compared with the existing technical solutions, the present invention is ingenious in conception, easy to use, and has good use and promotion value.

[0012] Furthermore, in order to ensure that the movement stroke of each group of hydraulic rods is consistent, a synchronization valve and a hydraulic pressure lock are also installed to control the synchronous oil supply of the hydraulic oil tanks on both sides of the same group.

[0014] Furthermore, the controller is also equipped with a wireless remote control handle, through which the hydraulic rod and the state of the servo motor can be controlled.

[0015] Furthermore, a handle is provided on the chassis to facilitate manual traction by construction workers.

[0016] Furthermore, a skin is applied on the side of the chassis.

[0017] A corner reflector is also installed on the side of the chassis or a fluorescent reflective layer is pasted on the skin of the outer side to improve visual safety in a dim environment.

[0018] Furthermore, a rubber layer for buffering is attached to the bottom of the chassis by bolts or glue to prevent the chassis from being damaged by bumps caused by lifting or lowering too quickly.

[0019] The method for using a large mass load docking device with an auxiliary lifting mechanism in loading and unloading a crawler-type insulated bucket arm vehicle is as follows: The chassis of the present invention is remotely driven out of the warehouse and moved to a suitable location on the site; The heavy cargo is driven by remote control to the middle of the chassis of the present invention and stops; At the same time, the front leg oil cylinder and the rear leg oil cylinder of the chassis of the present invention are controlled so that the chassis of the present invention is lifted as a whole to a suitable position and stops; The flatbed truck is slowly reversed in front of the chassis of the present invention; Control the two sets of hydraulic rods to descend and stop at the height of the flatbed truck compartment; Remote control to drive heavy cargo into the innermost part of the truck compartment; Controlling the two sets of hydraulic rods to rise, so that the driving wheels of the chassis of the present invention are flush with the height of the flatbed truck compartment; The truck is slowly reversed so that the driving wheels of the chassis of the present invention can be pressed against the end of the carriage; Control the retraction of the hydraulic lever at the front end; The remote control driving wheel slowly moves into the interior of the truck compartment and stops when the driven wheel touches the truck compartment; Control the rear hydraulic rod to retract; The driving wheel is continuously remotely controlled to slowly enter the interior of the carriage, and the chassis of the present invention stops after it completely enters the carriage.

[0020] Compared with the existing technical solutions, the present invention has the following technical advantages: (1) The crawler-type insulated boom truck auxiliary extension and lowering device realizes the loading and unloading process of the crawler-type insulated boom truck without damaging the mechanical structure of the vehicle itself. It is stable and reliable and can effectively extend the service life of the boom truck.
