Description

Technical Field

[0001] The utility model relates to the technical field of mechanical structural parts, in particular to a transport base for engineering mechanical structural parts. Background Art

[0002] Engineering machinery structural parts refer to the various parts that constitute the main structure of engineering machinery. They play the role of bearing and transmitting loads in engineering machinery equipment, and are also an important part of ensuring the stability and durability of mechanical equipment. According to their differences in structural characteristics and different locations of use, engineering machinery structural parts will have great differences in physical form and specific functions. In the production process of engineering machinery structural parts, process preparation stages such as material selection and preparation, formulation of processing routes and processing documents are required. In order to ensure the stability of engineering machinery structural parts during transportation, a transport base is required.

[0003] Common engineering machinery structural parts transport bases are usually composed of base frames, fixing devices, support and balance structures, lifting and handling devices, and protection and packaging structures. After the structural parts are fixed on the base frame by the fixing device, the support and balance structure and the protection and packaging provide stability and protection, and the lifting and handling device can be used for loading and unloading operations with external cranes and other equipment. This is a common structure and use method of the engineering machinery structural parts transport base. When transporting structural parts, the traditional engineering machinery structural parts transport base, because there is no shock absorbing device in the box, when the box body brakes suddenly or accelerates suddenly, the objects in the box will collide with the inner wall of the box, causing damage to the structural parts and affecting the normal use of the structural parts. For example, patent number CN217146861U is a kind of engineering machinery structural parts transport base. When the sliding block pushes the clamping plate to move, it can drive the piston plate to move. With the adhesion of the buffer, it can hinder the movement of the piston plate, thereby hindering the movement of the sliding block, and preventing the collision of the objects with the inner wall of the box body when the box body brakes suddenly or accelerates suddenly. However, in this way, since the clamping plate is connected to both sides of the sliding block, it can only provide buffering and collision prevention effects on both sides of the sliding block. The effect is limited and it is impossible to provide a comprehensive buffering effect around the sliding block, resulting in the sliding block still being likely to collide with the inner wall of the box. Therefore, a transportation base for engineering machinery structural parts is proposed. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a transport base for engineering machinery structural parts to solve the above-mentioned technical problem that a comprehensive buffering effect cannot be provided around the sliding block.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transport base for engineering machinery structural parts, comprising:

[0008] An outer shell, and a buffer cylinder arranged at the center of the outer shell, wherein the inner cavity of the buffer cylinder is respectively provided with a buffer spring and a limit plate, and the buffer spring and the limit plate are fitted to each other;

[0009] The connecting tube is arranged at the center of the outer shell and connected with the corresponding limit plate by insertion, and the inner end of the connecting tube is installed with a bifurcated rod, and the end of the bifurcated rod is provided with a buffer pad;

[0010] The base is arranged at the lower center of the inner cavity of the outer shell, and the corresponding parts around the base are tightly fitted with the buffer pad. After the inner cavity of the base is placed on the structural member, when the base moves inside the outer shell, it can drive the corresponding buffer pad, bifurcated rod and connecting tube to drive the limit plate to move along the inner wall of the buffer tube and squeeze the buffer spring. On the one hand, the buffer structure located around the outer shell is connected to the base, so that the base can be fully buffered around; on the other hand, a connection is inserted between the limit plate and the connecting tube, and when the buffer spring is used for a long time and the service life of the buffer spring is reduced, it is convenient to separate the limit plate from the connecting tube.

[0011] Preferably, the upper and lower parts of the front end of the buffer cylinder are rotatably connected to the side connecting rod, and the outer ends of the side connecting rods are inserted and connected with limit rods.

[0012] Preferably, the upper and lower parts of the rear end of the buffer cylinder are both provided with limiting cylinders, which are connected to the outer shell, and the front of the limiting cylinder is provided with limiting holes, which correspond to the inner ends of the limiting rods. The rear end of the side connecting rod can be inserted into the interior of the limiting cylinder through the limiting holes and rotated, so that the rear end of the side connecting rod is misaligned with the limiting holes, which, on the one hand, ensures the stability of the connection between the buffer cylinder and the outer shell; on the other hand, facilitates the disassembly and assembly of the buffer cylinder on the outer shell.

[0013] Preferably, the bottom of the base is evenly equipped with upper convex rods, and the bottom of the inner cavity of the outer shell is evenly equipped with lower convex rods corresponding to the upper convex rods. The base can move on the lower convex rods of the outer shell through the upper convex rods and play a certain buffering effect.

[0014] Preferably, a connecting cover is laterally added to the top of the outer shell, and a positioning block is installed at the corresponding lower part of the front of the connecting cover, and a positioning groove is opened at the corresponding upper part of the front of the outer shell. When the connecting cover is connected to the outer shell, the positioning block is inserted into the corresponding positioning groove, thereby avoiding misalignment of the connection between the outer shell and the connecting cover.

[0015] Preferably, a rotating shaft is transversely installed on the upper back of the outer shell and connected to the back of the connecting cover, and one end of the rotating shaft is coaxially connected to a driving motor. The driving motor drives the connecting cover to rotate in the same direction on the outer shell through the rotating shaft, thereby automatically controlling the opening and closing of the connecting cover.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a transport base for engineering machinery structural parts, which has the following beneficial effects:

[0018] The engineering machinery structural component transport base is constructed by placing the inner cavity of the base on the structural component. When the base moves inside the outer shell, it can drive the corresponding buffer pad, forked rod and connecting tube to drive the limit plate to move along the inner wall of the buffer tube and squeeze the buffer spring. In this way, on the one hand, the buffer structure located around the outer shell is connected to the base, so that a comprehensive buffering effect can be exerted on the surrounding of the base; on the other hand, a connection is inserted between the limit plate and the connecting tube. When the buffer spring is used for a long time and the service life of the buffer spring is reduced, it is convenient to separate the limit plate from the connecting tube.
