Description

Technical Field

[0001] The utility model belongs to the technical field of shuttle cars, and particularly relates to a shuttle car blocking mechanism. Background Art

[0002] At present, in the logistics warehousing system, the shuttle car is mainly used to automatically run on the guide rail and then transport the goods to the corresponding shelf. When the shuttle car moves to the end of the track, it will enter the lifting track, and the lifting equipment will lift the shuttle car to enter another track for continuous transportation.

[0003] For example, the Chinese patent of the prior art CN 221050638 U discloses a new type of four-way shuttle car reciprocating elevator, which is driven by a chain, the motor is controlled by frequency conversion speed regulation, the lifting car is equipped with a counterweight assembly, the guide rail mechanism makes a reciprocating up and down movement, and the lifting car is equipped with a chain drive mechanism so that the conveyed tray can automatically enter the lifting car of the elevator, and the track of the four-way shuttle car is designed on the conveying mechanism, and the four-way shuttle car can automatically enter the elevator to pick up and place goods.

[0004] For the lifting track in the prior art such as above, when the shuttle car stops at the end of the lifting track, due to the small friction between the shuttle car wheels and the track, the vehicle body will slide a certain distance after stopping. Moreover, although the elevator is equipped with a confirmation signal sensor when reaching each floor, if the sensor is damaged or fails, and there is no blocking design, the shuttle car will make a wrong judgment, which may lead to an accident of the shuttle car falling accidentally. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a shuttle car blocking mechanism, which has a simple structure and can effectively prevent the shuttle car from rushing out of the track after installation.

[0006] To achieve the above purpose, the utility model adopts the following content:

[0007] A shuttle car blocking mechanism provided by the utility model includes:

[0008] A base plate;

[0009] Mounting side plates, and two vertical mounting side plates are arranged in parallel at intervals on the surface of the base plate;

[0010] A swing body, which is arranged between the two mounting side plates, and the upper part of one side of the swing body is rotatably connected to a pin shaft, the pin shaft is fixed between the two mounting side plates, a torsion spring is sleeved on the pin shaft, an upper limit shaft and a lower limit shaft are respectively arranged on the swing body between the two mounting side plates in an up and down distribution, and the two first torsion arms of the torsion spring are between the upper limit shaft and the lower limit shaft and are respectively abutted against the upper limit shaft and the lower limit shaft;

[0011] A blocking body is obliquely arranged on the other side of the pendulum body, and an acute angle is formed between the blocking body and the pendulum body;

[0012] A pushing body is arranged between two mounting side plates. The pushing body is connected to a cylinder member, and the cylinder member is fixed on the substrate. A contact portion cooperating with the pushing body is arranged at the lower part of the pendulum body, and the up-and-down swinging movement of the pendulum body is realized through the pushing body.

[0013] According to a shuttle car blocking mechanism provided by the present utility model, the contact portion protrudes downward at the bottom end of the pendulum body, and an inclined contact surface is formed on one side of the contact portion. A rotatable roller is arranged on the pushing body, and the roller can rollingly contact with the inclined contact surface. In this way, when the cylinder body controls the pushing body to move back and forth, the roller will rollingly contact with the inclined contact surface of the contact portion, and thus the up-and-down swinging of the pendulum body is realized by pushing the contact portion, so as to adjust the inclined state of the blocking body.

[0014] According to a shuttle car blocking mechanism provided by the present utility model, a buffer body protruding upward is arranged on the surface of the substrate between the two mounting side plates, and the buffer body is located below the pendulum body. In this way, the limit position of the downward swing of the pendulum body is restricted by the buffer body, which is beneficial to the pushing body to play its corresponding effect.

[0015] According to a shuttle car blocking mechanism provided by the present utility model, the pendulum body includes two support plates arranged in parallel at intervals. On both sides of the upper end of the support plate, upward protruding ears are arranged.

The two ends of the telescopic spring are respectively connected to the blocking body and the installation block. In this way, the blocking body has a certain buffer and rebound effect through the action of the telescopic spring. When the blocking body touches the shuttle car, the blocking body will rebound, avoiding rigid collision with the shuttle car.

[0017] According to a shuttle car blocking mechanism provided by the present utility model, symmetric circular blocking portions are respectively arranged on both sides of the head end of the blocking body.

Specific Embodiments

[0022] To more clearly illustrate the present utility model, the following further describes the present utility model in conjunction with preferred embodiments. Those skilled in the art should understand that the specific content described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present utility model.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Please refer to Figure 1 as shown. An embodiment of the present utility model provides a shuttle car blocking mechanism, including a horizontal substrate 1; two vertically placed mounting side plates 2 are fixedly provided at intervals and in parallel on the surface of the substrate 1; a swing body 3 is arranged between the two mounting side plates 2, and the upper part of one side of the swing body 3 is rotatably connected to a pin shaft 21, and the pin shaft 21 is fixed between the two mounting side plates 2. In this way, the swing body 3 can rotate relative to the mounting side plates 2 through the pin shaft 21. A torsion spring 22 is sleeved on the pin shaft 21. An upper limit shaft 23 and a lower limit shaft 33 are respectively arranged between the two mounting side plates 2 and on the swing body 3 in an up-and-down distribution. The two first torsion arms of the torsion spring 22 are between the upper limit shaft 23 and the lower limit shaft 33 and are respectively in contact with the upper limit shaft 23 and the lower limit shaft 33. In the case where there is no external force acting on the swing body 3, the swing body 3 can always maintain a downward swinging posture through the torsion spring 22.

[0025] On the other side of the pendulum body 3, a blocking body 4 is inclinedly arranged, and an acute angle is formed between the blocking body 4 and the pendulum body 3; a pushing body 5 is also arranged between the two mounting side plates 2. The tail of the pushing body 5 is connected to a cylinder member 6, and the cylinder member 6 is fixed on the substrate 1. A contact portion 34 cooperating with the pushing body 5 is arranged at the lower part of the pendulum body 3. The up-and-down swinging action of the pendulum body 3 is realized through the pushing body 5, that is, the pushing body 5 approaches the contact portion 34 from one side, gradually jacks up the contact portion 34, and thus realizes the upward swing of the pendulum body 3.

[0026] Among them, the contact portion 34 protrudes downward at the bottom end of the pendulum body 3, and an inclined contact surface 341 is formed on one side of the contact portion 34. A rotatable roller 51 is arranged on the pushing body 5, and the roller 51 can rollingly contact with the inclined contact surface 341. That is to say, when the cylinder body controls the pushing body to move forward, the roller will gradually rollingly contact with the inclined contact surface of the contact portion and roll along the path of the inclined contact surface, thereby jacking up the contact portion, so that the pendulum body drives the blocking body to rotate upward to form a blocking posture; if this blocking posture needs to be released, only need to control the pushing body to retreat by the cylinder body, so that the roller gradually disengages from the inclined contact surface, so that the external force applied to the pendulum body disappears, and the pendulum body will return downward to the initial position under the action of the torsion spring, that is, the pendulum body drives the blocking body to rotate downward to unlock. In this way, the up-and-down swing of the pendulum body is realized by jacking the contact portion, so as to adjust the inclination state of the blocking body and form a blocking or unlocking state for the shuttle car.

[0027] In this embodiment, a buffer body 7 protruding upward is arranged on the surface of the substrate 1 between the two mounting side plates 2, and the buffer body 7 is located below the pendulum body 3. In this way, the limit position of the downward swing of the pendulum body is limited by the buffer body, which is beneficial to the pushing body to play its corresponding role and reduces the swing amplitude of the pendulum body from the initial position to the upward rotation to the blocking state.

[0028] In this embodiment, the pendulum body 3 includes two support plates 31 arranged in parallel at intervals. On both sides of the upper end of the support plate 31, upwardly protruding ears are arranged. An installation block 32 is arranged between the two support plates 31. The contact portion 34 is arranged at the middle position of the lower end of the support plate 31. The pin shaft is fixed between two of the ears, and the structure is compact.

[0029] Among them, the blocking body 4 and the pendulum body 3 are rotatably connected through a rotating shaft rod 41; the rotating shaft rod 41 is fixed between the two ears, and it is rotatably inserted into the middle part of the blocking body 4. The blocking body 4 is in a bent shape. A guide post 42 is arranged at the lower end of the blocking body 4. The guide post 42 is movably inserted into the installation block 32 inward. A telescopic spring 43 is sleeved on the guide post 42, and both ends of the telescopic spring 43 are respectively connected to the blocking body 4 and the installation block 32. In this way, the blocking body has a certain buffer and rebound effect through the action of the telescopic spring. When the blocking body touches the shuttle car, the blocking body will rebound to avoid rigid collision with the shuttle car.

[0030] Among them, symmetrical circular blocking portions 44 are respectively arranged on both sides of the head end of the blocking body 4. The circular blocking portions are used to prevent the shuttle vehicle from moving, ensuring the smooth progress of the production process.

[0031] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
