Description

Technical Field

[0001] The present invention relates to the technical field of material elevators, and in particular to a convenient-to-use material elevator for construction machinery. Background Art

[0002] Material lift, also known as lifting platform or freight lift, is a mechanical device that uses hydraulic or electric drive system to achieve vertical lifting. The lift can quickly move a large amount of goods in a short time, greatly reducing manpower and material costs. At the same time, it can also allow people to quickly reach the floor in buildings and other places, saving time.

[0003] After searching, the Chinese patent with the announcement number CN219297059U discloses a convenient-to-use construction machinery material lift, including: a base; a lifting plate is arranged at the upper end of the base, side grooves are opened on both sides of the inner wall of the bridge, an inner groove is opened on one side of the side groove, and the top surface of the inner groove is fixedly connected to the limit column. The rotation of the winch drum makes two sets of steel wire ropes wrap around the side surface of the winch drum. When the limit block contacts the buffer pad, it will drive the slide bar to slide upward inside the slide groove. The lifting plate can be buffered by the cooperation of the limit plate and the spring. When the force plate moves to the bottom of the limit column, the limit block cannot move upward. At this time, the lifting plate can be limited to prevent the material from colliding with the top of the bridge. The universal wheel can be used to facilitate the movement of the equipment. The turntable drives the screw rod to rotate. At this time, the screw rod drives the positioning plate to move downward. When the positioning plate contacts the ground, the equipment can be fixed to prevent the equipment from moving. It is very convenient to use. However, this solution still has the following shortcomings in actual use: Although the material elevator greatly improves the efficiency of material handling in the process of vertically lifting various materials, in actual operation, especially for bulk materials, after they are lifted to a specified height by the lifting plate, they often need to rely on workers to manually unload them one by one. This process is not only cumbersome to operate, increasing labor costs, but also inefficient. More importantly, there is often a certain gap between the lifting plate and the unloading platform, which is caused by minor errors in the design, manufacturing or installation process, as well as wear and tear after long-term use. Although this gap seems small, it may become a potential risk point for materials to slip.

[0004] Therefore, it is necessary to design a construction machinery material lifting device that is easy to use to solve the above problems. Summary of the invention

In the process of the driving assembly driving the material storage box 8, the unloading method of the material storage box 8 can be adjusted by the guide assembly, so that the material storage box 8 can be moved horizontally for unloading and can be turned over for unloading, which is more convenient to use. When the lifting box 4 moves to the top of the bracket 2, the buffer locking assembly can buffer and lock the lifting box 4 to ensure that the lifting box 4 is more stable when used at a high place.

The connecting rope 75 and the cable 79 are both made of high-strength metal materials. When the lifting box 4 is lifted, the hoisting motor 77 can be turned on to drive the winding drum 78 to rotate to reel the cable 79. During the reeling process of the cable 79, the lifting box 4 can be driven to move along the bracket 2 by the fixed pulley 72 and the movable pulley 73 to achieve the lifting of the lifting box 4. Similarly, the lifting box 4 can be moved downward when the reel 78 is unwound. During the whole process, the pulley group formed by the fixed pulley 72 and the movable pulley 73 makes it possible to use less force to lift the lifting box 4, thereby ensuring that the lifting of the lifting box 4 is more labor-saving and safe.

[0020] Reference Figure 3 , Figure 4 The driving assembly includes: a slide plate 91, which is slidably mounted on the inner bottom surface of the lifting box 4; two slide grooves 92, which are symmetrically opened on the inner wall of the lifting box 4; two sliders 93, which are symmetrically fixedly mounted on the ends of the slide plate 91, and the sliders 93 are slidably connected to the slide grooves 92; two rotating racks 94, which are symmetrically arranged on one side of the top surface of the slide plate 91, and the top surface of the rotating rack 94 is fixedly connected to the bottom surface of the material storage box 8, and the bottom surface of the material storage box 8 is symmetrically fixedly mounted on one side away from the rotating rack 94 with a support rod 95; a threaded groove 96, which is opened on the side of the slide plate 91; a servo motor 97, which is fixedly mounted on the side of the lifting box 4, and a control switch 1 is arranged on the side of the lifting box 4 4.

During the extension process, the material can be unloaded in two different ways through the guide component, ensuring a faster unloading speed of the material. After unloading, the servo motor 97 can be reversed to drive the material storage box 8 to reset.

If the baffle 104 is located in the give way groove 105, the material storage box 8 can be directly moved horizontally to the unloading platform for unloading. If the baffle 104 is located in the guide port 101 and is tilted, the material storage box 8 can be turned over during the horizontal movement to realize the tipping bucket unloading, which is more convenient to use. At the same time, when the tipping bucket is unloading, when the support rod 103 slides along the lifting port 102, the material storage box 8 can be shaken under the action of the rubber strip 107 to avoid the residue of material inside the material storage box 8.

[0022] Reference Figure 2 , Figure 7 , Figure 8 The buffer locking assembly includes: a connecting plate 121, which is fixedly installed on the side of the fixed plate 11; a top rod 122, which is arranged on the top surface of the connecting plate 121; a buffer plate 123, which is fixedly installed on the bottom end of the top rod 122, and a rubber plate 13 is arranged on the bottom surface of the buffer plate 123; two springs 124, which are symmetrically fixedly installed between the connecting plate 121 and the buffer plate 123; a fixing frame 125, which is fixedly installed on the bottom surface of the fixed plate 11; a limiting rod 126, which is arranged on the side of the fixing frame 125; a spring 127, which is sleeved on the limiting rod 126; a control mechanism, which is arranged on the fixed plate 11; when the lifting box 4 is lifted to the top of the bracket 2, the top surface of the lifting box 4 can squeeze the buffer plate 123, and under the action of the spring 124, the buffer plate 123 can buffer the lifting box 4.

[0023] Reference Figure 7 , Figure 8The control mechanism includes: a rotating shaft 128, which is rotatably mounted on the side of the fixed plate 11; a vertical plate 129, which is fixedly mounted on the end of the rotating shaft 128; a transmission gear 1210, which is sleeved on the rotating shaft 128; a transmission rack 1211, which is fixedly mounted on the top of the top rod 122 through a mounting frame, and the transmission rack 1211 is meshed with the transmission gear 1210; a second magnetic piece 1212, which is fixedly mounted on the end of the limit rod 126; a third magnetic piece 1213, which is fixedly mounted on one end of the vertical plate 129; an electromagnet 1214, The end of the vertical plate 129 away from the magnetic sheet 3 1213 is fixedly mounted, and the relative magnetic poles of the electromagnet 1214, the magnetic sheet 3 1213 and the magnetic sheet 2 1212 are opposite; the limit opening 1215 is provided on the side of the lifting box 4, and the limit rod 126 is adapted to the limit opening 1215; in the initial state, under the action of the magnetic force of the magnetic sheet 3 1213 and the magnetic sheet 2 1212 attracting each other, the limit rod 126 is located on the fixed frame 125 on the side close to the magnetic sheet 3 1213, and as the lifting box 4 pushes the buffer plate 123 The buffer plate 123 can drive the top rod 122 to move upward along the connecting plate 121 and drive the transmission rack 1211 to move. When the transmission rack 1211 moves, it meshes with the transmission gear 1210, thereby driving the transmission gear 1210, the rotating shaft 128 and the vertical plate 129 to rotate. When the vertical plate 129 rotates, the magnetic piece 3 1213 at the end can be staggered with the magnetic piece 2 1212, so that the limit rod 126 slides along the fixing frame 125 under the action of the spring 2 127, and the end can enter the side of the lifting box 4 The limit opening 1215 of the lifting box 4 is locked, and the electromagnet 1214 at the end of the vertical plate 129 can be rotated to a position opposite to the magnetic piece 1212. When the lifting box 4 moves downward, the electromagnet 1214 needs to be energized first. At this time, under the action of the magnetic force of the electromagnet 1214 and the magnetic piece 1212, the limit rod 126 can slide in the opposite direction to move out of the limit opening 1215, thereby releasing the limit on the lifting box 4. At this time, the hoisting motor 77 can be reversed to move the lifting box 4 downward.

[0024] The specific working principle of the present invention is as follows: When in use, the staff can first place the materials to be lifted inside the material storage box 8 in the lifting box 4, and then drive the lifting box 4 through the lifting assembly so that the lifting box 4 is lifted along the bracket 2 through the guide wheels 6 and the guide grooves 5. When the lifting box 4 is lifted to the top of the bracket 2, the driving assembly can be turned on to drive the material storage box 8 to move out of the lifting box 4 to the top of the unloading platform, and the staff can unload the materials in the material storage box 8. In the process of the driving assembly driving the material storage box 8, the unloading mode of the material storage box 8 can be adjusted through the guide assembly, so that the material storage box 8 can be moved horizontally for unloading and can be turned over for unloading, which is more convenient to use. When the lifting box 4 moves to the top of the bracket 2, the buffer locking assembly can buffer and lock the lifting box 4, ensuring that the lifting box 4 is more stable when used at a high place. Specifically, when the lifting box 4 is lifted, the hoisting motor 77 can be turned on to drive the winding drum 78 to rotate to reel in the cable 79. During the reeling process of the cable 79, the lifting box 4 can be driven to move along the bracket 2 by the fixed pulley 72 and the movable pulley 73 to lift the lifting box 4. Similarly, when the winding drum 78 is unwound, the lifting box 4 can be moved downward. During the whole process, the pulley group formed by the fixed pulley 72 and the movable pulley 73 makes it possible to use less force to lift the lifting box 4, thereby ensuring that the lifting of the lifting box 4 is more labor-saving and safe. When the lifting box 4 is lifted to the top of the bracket 2, the top surface of the lifting box 4 can squeeze the buffer plate 123. Under the action of the spring 124, the buffer plate 123 can buffer the lifting box 4. In the initial state, under the action of the magnetic force of the magnetic sheet 3 1213 and the magnetic sheet 2 1212, the limit rod 126 is located on the fixed frame 125 on the side close to the magnetic sheet 3 1213. As the lifting box 4 pushes the buffer plate 123, the buffer plate 123 can drive the push rod 122 to move upward along the connecting plate 121 and drive the transmission rack 1211 to move. When the strip 1211 moves, it meshes with the transmission gear 1210, thereby driving the transmission gear 1210, the rotating shaft 128 and the vertical plate 129 to rotate. When the vertical plate 129 rotates, the magnetic sheet 3 1213 at the end can be staggered with the magnetic sheet 2 1212, so that the limiting rod 126 slides along the fixing frame 125 under the action of the spring 2 127, and the end can enter the limiting opening 1215 on the side of the lifting box 4, so as to realize the limiting locking of the lifting box 4, and at this time, the electromagnet 1214 at the end of the vertical plate 129 can rotate to a position opposite to the magnetic sheet 2 1212; With the locking of the lifting box 4 completed, the staff can drive the servo motor 97 through the control switch 14 to move the material box 8 to unload. Before unloading, the staff can adjust the unloading method according to the material situation. The baffle 104 can be rotated during adjustment. If the baffle 104 is located in the give way groove 105, the material box 8 can be directly moved horizontally to the unloading platform for unloading. If the baffle 104 is located in the guide port 101 and is tilted, the material box 8 can be turned over during the horizontal movement to realize the tipping bucket unloading, which is more convenient to use. At the same time, when the tipping bucket is unloading, the support rod 103 slides along the lifting port 102 and the material box 8 can be shaken under the action of the rubber strip 107 to avoid the residue of material inside the material box 8. When unloading, the servo motor 97 can drive the transmission screw 98 to rotate. The transmission screw 98 is screwed with the thread groove 96, so that the slide plate 91 can be driven to slide along the slide groove 92 through the slide block 93 and extend out of the lifting box 4. In the process of extending, if the unloading is horizontal, the support rod 103 slides along the guide port 101. If the bucket is unloading, the support rod 103 can slide along the lifting port 102 under the action of the baffle 104, so that the rear end of the material storage box 8 is lifted and the material storage box 8 is rotated through the rotating frame 94. The servo motor 97 can be reversed after the unloading is completed to drive the material storage box 8 to reset. When the lifting box 4 moves downward, the electromagnet 1214 needs to be energized first. At this time, under the action of the magnetic force of the electromagnet 1214 and the magnetic sheet 1212, the limit rod 126 can slide in the opposite direction to move out of the limit port 1215, thereby releasing the limit on the lifting box 4. At this time, the winch motor 77 can be reversed to move the lifting box 4 downward.
