Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a novel self-unloading elevator. Background Art

[0002] In the modern construction industry, with the increasing number of high-rise buildings, the demand for vertical transportation of construction materials has also increased. In particular, during construction projects, concrete pouring materials need to be efficiently and safely transported from the ground to the required height. This transportation process not only affects the construction schedule but also has a direct impact on the safety and efficiency of the construction site. Traditionally, this vertical transportation task has been mainly accomplished by hoists. As a key construction machine, hoists use their internal lifting mechanism to smoothly raise buckets loaded with construction materials to a specified height. However, once the bucket reaches the required height and is ready for unloading, ensuring that it is stably locked to prevent safety accidents caused by accidental slipping or shaking has become a pressing issue.

[0003] Existing locking mechanisms have limitations in design and application. First, they are often complex, incorporating multiple precision mechanical components and transmission mechanisms. This not only increases the difficulty of manufacturing and maintenance, but also increases overall manufacturing costs. Second, the complex structure often means cumbersome installation, requiring specialized technicians to conduct lengthy debugging and calibration to ensure the accuracy and reliability of the locking mechanism. Summary of the Invention

[0004] In view of the above problems existing in the existing hoists, the present invention aims to provide a new self-unloading hoist with simple structure, easy installation and low cost.

[0005] The specific technical solutions are as follows:

[0006] A new self-unloading hoist, comprising:

[0007] pillars;

[0008] A rotating member, one end of which is rotatably mounted on the column, and the other end of which is tilted upward and forms a locking groove;

[0009] an elastic member, the elastic member being provided between the rotating member and the column and being used for providing a rotational return torque to the rotating member;

[0010] A material barrel assembly is used to store casting materials. The material barrel assembly slides longitudinally on the column. A locking piece is formed on the material barrel assembly. When the locking piece moves upward with the material barrel assembly, the bottom of the other end of the rotating piece can be pushed upward so that the locking piece is placed in the locking groove. When the locking piece presses down the bottom of the locking groove, the side wall of the locking groove contacts the locking piece outward to lock the material barrel assembly.

[0011] As a further improvement and optimization of this solution, the top of the other end of the rotating member is extended outward along the inclination direction of the rotating member. When the barrel assembly presses down the top of the other end of the rotating member through the locking member, the locking member can push the other end of the rotating member downward to move the locking member to the bottom of the rotating member.

[0012] As a further improvement and optimization of this solution, the elastic member includes a torsion spring, the rotating member is rotatably mounted on the column via a pin, and the torsion spring is sleeved on the outside of the pin and connected between the rotating member and the column;

[0013] As a further improvement and optimization of this solution, the elastic member includes a tension spring arranged above the rotating member, and the tension spring is connected between the rotating member and the column.

[0014] As a further improvement and optimization of this solution, the elastic member includes a torsion spring and a tension spring;

[0015] The rotating member is rotatably mounted on the column via a pin shaft, and the torsion spring is sleeved on the outside of the pin shaft and connected between the rotating member and the column;

[0016] The tension spring is arranged above the rotating member and connected between the rotating member and the column.

[0017] As a further improvement and optimization of this solution, a lifting mechanism is also included which is installed on the column and is used to lift the bucket assembly longitudinally.

[0018] As a further improvement and optimization of this solution, the lifting mechanism includes a pulling rope, one end of which is connected to the bucket assembly and is operable to pull the bucket assembly longitudinally.

[0019] As a further improvement and optimization of this solution, the barrel assembly includes:

[0020] a lifting frame, the lifting frame sliding longitudinally on the column;

[0021] A barrel body, the barrel body is connected to the lifting frame, and the bottom side of the barrel body has a discharge port;

[0022] The blocking side panel is hinged on the barrel body and cooperates with the discharge port to block the material. One end of the pulling rope is connected to the blocking side panel. When the barrel assembly is in a locked state, the blocking side panel can be automatically flipped outward by lowering one end of the pulling rope to open the discharge port.

[0023] As a further improvement and optimization of this solution, the barrel assembly includes:

[0024] A lifting frame, wherein the lifting frame has a support platform, and one end of the pulling rope is connected to the support platform;

[0025] The barrel body is placed on the supporting platform.

[0026] As a further improvement and optimization of this solution, the support platform is rotatably connected to the lifting frame.

[0027] Compared with the prior art, the above technical solution has the following positive effects:

[0028] (1) The present invention utilizes the ingenious cooperation among the rotating member, the locking groove on the rotating member, the locking member, and the elastic member to achieve the locking effect of the barrel assembly, which not only simplifies the structure and reduces the difficulty of manufacturing, installation and maintenance, but also reduces the production cost.

[0029] (2) In the present invention, the top of the other end of the rotating member is extended outward along the inclination direction of the rotating member. The purpose is to prevent the locking member from being disengaged from the other end of the rotating member and then being placed in the locking groove again when the locking member is pressed down on the top of the other end of the rotating member, thereby preventing the barrel assembly from being unlocked, thereby improving the operating reliability of the equipment.

[0030] (3) In the present invention, when the barrel assembly is in a locked state, the electric winch can be used to unwind the lifting rope, and the sealing side panels can be automatically opened under the thrust of their own weight and the cast material inside the barrel body to achieve automatic unloading. This design can reduce the center of gravity shift of the machine during the unloading process, thereby avoiding the tilting and shaking of the column. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Figure 1 This is a structural diagram of a new self-unloading hoist of the utility model. Figure 2 This is a schematic diagram of the structure of the rotating parts of a new self-unloading hoist of the utility model. Figure 3 This is a structural diagram of a bucket assembly in one embodiment of a new self-unloading elevator of the utility model. Figure 4This is a structural diagram of a bucket assembly in another embodiment of a novel self-unloading elevator of the present invention. Figure 1-4 As shown, a new type of self-unloading elevator of a preferred embodiment is shown, including a column 1, a rotating part 2, an elastic part and a bucket assembly 3 for storing casting materials. One end of the rotating part 2 is rotatably arranged on the column 1, and the other end of the rotating part 2 is inclined upward and forms a locking groove 21. The elastic part is arranged between the rotating part 2 and the column 1, and is used to provide a rotational reset torque to the rotating part 2. The bucket assembly 3 slides longitudinally on the column 1, and a locking part 31 is formed on the bucket assembly 3. When the locking part 31 moves upward with the bucket assembly 3, the bottom of the other end of the rotating part 2 can be pushed upward to place the locking part 31 in the locking groove 21, and when the locking part 31 presses down the bottom of the locking groove 21, the side wall of the locking groove 21 contacts the locking part 31 outward to lock the bucket assembly 3. In actual use, the bucket assembly 3 carries the casting material and slides upward. When the locking member 31 contacts the bottom of the other end of the rotating member 2, the rotating member 2 is pushed upward to rotate the rotating member 2 upward. When the locking member 31 is out of contact with the rotating member 2, the rotating member 2 is reset under the action of its own weight and the elastic force provided by the elastic member, so that the locking member 31 is placed in the locking groove 21. Then, the bucket assembly 3 slides downward. When the locking member 31 contacts the bottom of the locking groove 21 and presses down the rotating member 2, since the other end of the rotating member 2 is initially in an inclined upward state, the other end of the rotating member 2 is It has a downward rotation movement tendency. When the side wall of the locking groove 21 contacts the locking member 31, the inner wall of the locking groove 21 has an outward resistance force on the locking member 31 (at this time, the distance between the contact point between the inner wall of the locking groove 21 and the locking member 31 and the rotating end of the rotating member 2 will tend to be greater than the distance between the rotating end of the rotating member 2 and the locking member 31 as the rotating member 2 continues to rotate downward). At this time, the locking member 31 will prevent the rotating member 2 from continuing to rotate downward, so that the inner wall of the rotating member 2 forms a stable support structure for the locking member 31, thereby completing the locking effect of the barrel assembly 3.

[0040] In this embodiment, the rotating part 2, the locking groove 21 on the rotating part 2, the locking part 31, and the elastic part are cleverly coordinated with each other to achieve the locking effect of the barrel assembly 3. This not only simplifies the structure and reduces the difficulty of manufacturing, installation and maintenance, but also reduces the production cost.

[0041] Furthermore, as a preferred embodiment, the top of the other end of the rotating member 2 is extended outward along the inclination direction of the rotating member 2. When the barrel assembly 3 presses down the top of the other end of the rotating member 2 through the locking member 31, the locking member 31 can push the other end of the rotating member 2 downward to move the locking member 31 to the bottom of the rotating member 2. When the locking piece 31 is in contact with the top of the other end of the rotating member 2, the other end of the rotating member 2 can be pressed down by the elastic action of the elastic member, and the locking piece 31 is located below the rotating member 2, and the bucket assembly 3 can continue to slide down to the ground for loading.

[0042] In this embodiment, the top of the other end of the rotating member 2 is extended outward along the inclination direction of the rotating member 2. Its purpose is to prevent the locking member 31 from being disengaged from the other end of the rotating member 2 and being placed in the locking groove 21 again when the locking member 31 is disengaged from the other end of the rotating member 2, resulting in the inability to unlock the barrel assembly 3, thereby improving the operating reliability of the equipment.

[0043] Furthermore, as a preferred embodiment, it also includes a lifting mechanism installed on the column 1 and used to longitudinally lift the bucket assembly 3.

[0046] In one embodiment, the lifting mechanism also includes an electric winch (not shown in the figure) installed on the ground and a fixed pulley (not shown in the figure) installed on the top of the column 1, and the other end of the lifting rope 4 is wound around the fixed pulley and connected to the drum of the electric winch.

[0047] Furthermore, as a preferred embodiment, the barrel assembly 3 includes a lifting frame 34, a barrel body 32 and a blocking side plate 33. The lifting frame 34 slides longitudinally on the column 1, the barrel body 32 is connected to the lifting frame 34, and the bottom side of the barrel body 32 has a discharge port. The blocking side plate 33 is hinged to the barrel body 32 and cooperates with the discharge port to block the discharge port. One end of the lifting rope 4 is connected to the blocking side plate 33. When the barrel assembly 3 is in a locked state, the blocking side plate 33 can be automatically flipped outward by lowering one end of the lifting rope 4 to open the discharge port.

[0048] In this embodiment, when the barrel assembly 3 is in a locked state, the lifting rope 4 can be unwound by an electric winch, and the blocking side panel 33 is automatically opened under the thrust of its own weight and the pouring material inside the barrel body 32 to achieve automatic unloading. This design can reduce the center of gravity deviation of the machine during the unloading process, thereby avoiding the tilting and shaking of the column 1.

[0049] In one embodiment, support legs 331 are provided on both sides of the bottom of the blocking side panel 33. When the blocking side panel 33 is opened, the support legs 331 can be supported on the plane of the casting point to stabilize the blocking side panel 33 in the open state.

[0050] More preferably, a slide rail is provided on the column 1 in the longitudinal direction, and a plurality of rollers 35 are provided on the side of the lifting frame 34 away from the barrel body 32 for longitudinal rotation.
