Description

Technical Field

[0001] The utility model relates to the field of containers, in particular to a container spreader buffer device. Background Art

[0002] A container is a group of tools that can be loaded with packaged or unpackaged goods for transportation and is easy to load, unload and handle with mechanical equipment. A spreader is required during the transportation of the container, and a buffer device needs to be installed on the container spreader. The buffer device is an important component of the container spreader and is designed to reduce the impact and vibration of the spreader during the lifting process to ensure the safety and stability of the lifting operation.

[0003] A search revealed a utility model container spreader with announcement number CN208440145U, comprising a quadruple drum, a spreader, and four wire rope securing devices. A spreader pulley is connected to each of the four corners of the spreader's top side. Pulley covers are symmetrically located on either side of the spreader pulleys. A hydraulic caliper brake device is mounted on each of the spreader pulleys. The hydraulic caliper brake device includes a base fixed to the edges of the two pulley covers, hingedly connected to a first brake arm and a second brake arm. The first and second brake arms are located on either side of the fixed pulley, respectively. The middle portions of the first and second brake arms are hingedly connected to the base via pins. Brake linings for clamping the fixed pulley are symmetrically fixed to the inner sidewalls of the first and second brake arms near the spreader pulleys. A hydraulic cylinder is connected between the ends of the first and second brake arms away from the spreader pulleys, with both ends of the hydraulic cylinder hingedly connected to the first and second brake arms. This utility model ensures secure braking of the fixed pulley, preventing deflection and ensuring safe use.

[0004] Most of the existing container spreaders do not have anti-collision buffer devices during the container lifting process, so that accidental collisions during the lifting process can easily cause the goods in the container to shake and cause damage. The container spreader in the above-mentioned comparative case adjusts the offset of the container spreader through the design of a four-link drum, but the comparative example lacks corresponding buffer settings. Therefore, even if the offset can be adjusted, a collision will cause the goods in the container to shake. At the same time, during the lifting process of the spreader, when the lifting lugs are close to the ground or above the container, the impact force they will directly receive causes wear of the lifting lugs.

[0005] Therefore, it is necessary to invent a container spreader buffer device to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a buffer device for a container spreader, when the main frame of the container spreader is lowered to the container, the base and rubber pads on both sides of the main frame of the container spreader first contact the container, and the damping rod and the second damping spring above the base play a role of buffering and shock absorption, thereby preventing the impact force of the lowering lifting ear from directly colliding with the container and causing wear, so as to solve the problem that the container spreader in the above-mentioned comparative case proposed in the above-mentioned background technology adjusts the offset of the container spreader through the design of a four-link drum, but the comparative example lacks a corresponding buffer setting, so that even if the offset can be adjusted, the collision will cause the cargo in the container to shake, and at the same time, when the lifting ear is close to the ground or above the container during the lifting of the spreader, it will directly receive the impact force causing wear of the lifting ear.

[0007] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: a container spreader buffer device, comprising a buffer mechanism and a container spreader main frame;

[0008] The buffer assembly is installed on the front and rear sides of the container spreader main frame for buffering.

The front and rear sides of the container spreader main frame are fixedly connected with reinforcing ribs, and lifting ears are provided around the bottom of the container spreader main frame.

[0009] Preferably, the buffer mechanism includes a fixing frame, which is fixedly arranged inside both sides of the buffer mechanism, and the inner sides of the fixing frame are fixedly connected with sliding rods, and the outer sides of the sliding rods are slidably connected with telescopic plates, and tension springs are provided in front of the telescopic plates, and the front sides of the telescopic plates are fixedly connected with telescopic rods, one end of the telescopic rod is fixedly connected with a buffer plate, and a first damping spring is provided on the outside of the telescopic rod.

[0013] Preferably, four groups of bases and rubber pads are provided, and the four groups are distributed at equal intervals on the main frame of the container spreader.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The utility model can not only generate buffering during left and right collisions through the arrangement of the buffer mechanism, the main frame of the container spreader, the lifting eyes and the buffer assembly, but also has a certain buffer space when the lifting eyes are close to the ground or above the container, avoiding wear caused by direct hard contact. When the main frame of the container spreader is lowered to the container, the base and rubber pads on both sides of the main frame of the container spreader first contact the container, and the damping rod and the second damping spring above the base play a role of buffering and shock absorption, thereby avoiding the impact force of the lowering lifting eyes directly colliding with the container and causing wear.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The utility model provides Figure 1-4 A container spreader buffer device shown includes a buffer mechanism 1 and a container spreader main frame 2;

[0025] The buffer assembly 7 is installed on the front and rear sides of the container spreader main frame 2 for buffering. The inner sides of the container spreader main frame 2 are fixedly connected with I-beams 3, and the inner sides of the I-beams 3 are fixedly provided with hooks 4. The front and rear sides of the container spreader main frame 2 are fixedly connected with reinforcing ribs 5. The lower side of the container spreader main frame 2 is provided with lifting ears 6. When the container spreader main frame 2 is lowered onto the container, the bases 705 and rubber pads 706 on both sides of the container spreader main frame 2 first contact the container, and the damping rod 703 and the second damping spring 704 above the base 705 play a role in buffering and shock absorption, thereby avoiding direct collision with the impact force of the lifting ears 6 when they fall. The container is caused to wear and tear. When the subsequent container is lifted, the buffer plates 106 on both sides of the container spreader main frame 2 touch other objects, the telescopic rod 105 behind the buffer plate 106 is used to push the telescopic plate 103 to extend and retract in the fixed frame 101, and a plurality of tension springs 104 are provided between the telescopic plate 103 and the fixed frame 101 to play a role of buffering and stretching. At the same time, the first damping spring 107 outside the telescopic rod 105 behind the buffer plate 106 can play a role of shock absorption and buffering, avoiding direct collision with the container spreader main frame 2 to cause overall shaking, which not only affects the goods inside the container, but also causes wear and tear on the container spreader main frame 2.

[0026] like Figure 1 、 Figure 2 and Figure 3As shown, the buffer mechanism 1 includes a fixed frame 101, which is fixedly arranged inside both sides of the buffer mechanism 1, and the inner sides of the fixed frame 101 are fixedly connected with sliding rods 102, and the outer side of the sliding rod 102 is slidably connected with a telescopic plate 103, and a tension spring 104 is provided in front of the telescopic plate 103, and the front of the telescopic plate 103 is fixedly connected with a telescopic rod 105, one end of the telescopic rod 105 is fixedly connected with a buffer plate 106, and a first damping spring 107 is provided on the outside of the telescopic rod 105, and the telescopic rod 105 behind the buffer plate 106 is used to push the telescopic plate 103 to extend and retract in the fixed frame 101, and a plurality of tension springs 104 are provided between the telescopic plate 103 and the fixed frame 101, which play a role of buffering and stretching. At the same time, the first damping spring 107 on the outside of the telescopic rod 105 behind the buffer plate 106 can play a role of shock absorption and buffering to avoid direct collision with the container spreader main frame 2 and causing overall shaking.

[0027] like Figure 2 and Figure 3 As shown, the telescopic plate 103 is slidably connected to the fixed frame 101 through the sliding rod 102, and multiple groups of tension springs 104 are provided. The multiple groups of tension springs 104 are installed on one side of the telescopic plate 103 and inside the fixed frame 101. When the buffer plate 106 is subjected to pressure collision, it will push the telescopic plate 103 at one end of the rear telescopic rod 105, so that the telescopic plate 103 moves in the fixed frame 101. During the movement, multiple tension springs 104 are provided between the telescopic plate 103 and the fixed frame 101, so that the telescopic plate 103 plays a rebound and stretching role, thereby enhancing the buffering performance.

[0028] like Figure 2 and Figure 3 As shown, the buffer plate 106 is slidably connected to the fixing frame 101 through the telescopic rod 105, and the first damping spring 107 is arranged between the fixing frame 101 and the buffer plate 106. When the buffer plate 106 is subjected to the impact force of the collision, it pushes the multiple telescopic rods 105 at the rear, and the first damping spring 107 outside the telescopic rod 105 has the effect of squeezing and buffering, thereby buffering the buffer plate 106.

[0029] like Figure 1 and Figure 4As shown, the buffer assembly 7 includes a mounting plate 701, which is mounted on the front and rear sides of the container spreader main frame 2. Bolts 702 are threaded through both sides of the mounting plate 701. Damping rods 703 are provided inside both sides of the mounting plate 701. A second damping spring 704 is provided outside the damping rod 703. The lower end of the damping rod 703 is fixedly connected to a base 705. A rubber pad 706 is provided below the base 705. When the container spreader main frame 2 descends onto the container, the bases 705 and rubber pads 706 on both sides of the container spreader main frame 2 first contact the container, and the damping rod 703 and the second damping spring 704 above the base 705 play a role in buffering and shock absorption, thereby preventing the impact force of the lifting eye 6 from directly colliding with the container and causing wear.

[0030] like Figure 4 As shown, four groups of bases 705 and rubber pads 706 are provided, and the four groups are evenly spaced on the main frame 2 of the container spreader. By setting the four groups of bases 705 and rubber pads 706, the impact force during the descent process is dispersed and buffered, thereby preventing the impact force of the descent of the lifting lug 6 from directly touching the container and causing wear.

[0031] The working principle of this utility model is as follows: first, the crane and the wire rope are connected to the hook 4 on the I-beam 3 inside the main frame 2 of the container spreader, and then the crane lifts the entire main frame 2 of the container spreader, and then moves it to the top of the required transport container, and then slowly lowers the main frame 2 of the container spreader, and first contacts the container through the base 705 and rubber pads 706 on both sides of the main frame 2 of the container spreader, and utilizes the damping rod 703 and the second damping spring 704 above the base 705 to play a role in buffering and shock absorption, thereby preventing the impact force of the lowering ear 6 from directly colliding with the container and causing wear, and then hang the ear 6 in the buckle groove around the container, and then rotate the ear 6 to lock the ear 6 with the buckle groove around the container, and then start the crane to lift the main frame 2 of the container together with the container, when the container is accidentally lifted and the sides are When a collision occurs, the buffer plates 106 on both sides of the container spreader main frame 2 will first touch the colliding object, and the impact force generated by the collision contacts the buffer plates 106, and the telescopic rod 105 behind the buffer plates 106 is used to push the telescopic plates 103 to retract and retract in the fixed frame 101, and a plurality of tension springs 104 are provided between the telescopic plates 103 and the fixed frame 101, thereby pulling the telescopic plates 103 to play a buffering role, and at the same time, the first damping spring 107 outside the telescopic rod 105 behind the buffer plates 106 also plays a buffering role when it is squeezed. In this way, through two layers of buffering, objects are prevented from directly colliding with the container spreader main frame 2 and causing overall shaking, which not only affects the goods inside the container, but also causes wear and tear on the container spreader main frame 2. In this way, the use process of the container spreader buffer device is completed.

[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
