Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a conveyor belt assembly and an elevator. Background Technology

[0002] A hoist is a mechanical device used for vertical or inclined material conveying. It can efficiently lift various bulk and lumpy materials from a low place to a high place and is widely used in many fields such as mining, metallurgy, chemical industry, and construction. The working principle of a hoist is to use a power-driven conveyor belt carrying device to continuously lift the material.

[0003] After prolonged use, conveyor belts undergo irreversible fatigue deformation, leading to loosening and slippage on the rollers, which affects the effectiveness of the belt drive. Furthermore, once the elevator is installed, the positions of the drive and driven rollers are fixed. When adjusting the conveyor belt tension, both rollers must be removed and replaced with a new belt to ensure proper tension. This consumes significant manpower and time, reducing the efficiency of conveyor belt tension adjustment. Utility Model Content

[0004] The purpose of this invention is to provide a conveyor belt assembly and a lifting machine to improve the tension adjustment efficiency of the conveyor belt.

[0005] To achieve this objective, the technical solution adopted by this utility model is as follows:

[0006] A conveyor belt assembly includes a conveyor frame, a drive roller, a driven roller, a drive unit, and a conveyor belt. The drive roller and the driven roller are spaced apart on the conveyor frame along the length direction. The conveyor belt is sleeved on the drive roller and the driven roller. The drive unit is drively connected to the drive roller.

[0007] The conveyor belt assembly further includes two adjustment components, each including a slide table and a locking element. The slide tables of the two adjustment components are spaced apart on the conveyor frame along the width direction. The two ends of the driven roller are rotatably mounted on the corresponding slide tables along the axial direction. The position of the slide tables is adjustable along the length direction. The locking element is configured to lock or unlock the relative position of the slide tables and the conveyor frame.

[0008] As an optional solution for the conveyor belt assembly, the conveyor frame is provided with a groove along the length direction, and each slide is slidably disposed in the corresponding groove; the locking member locks or unlocks the position of the slide in the groove.

[0009] As an optional solution for the conveyor belt assembly, pressure plates are provided on the top ends of both sides of the chute extending inward along the width direction, and a first opening is formed between the two pressure plates so that the longitudinal section of the chute is an inverted T-shape.

[0010] The top of the slide table is provided with two stepped surfaces spaced apart. When the slide table is slidably disposed in the slide groove, the two pressure plates respectively overlap the corresponding stepped surfaces.

[0011] As an alternative to the conveyor belt assembly, one end of the chute extends through the conveyor frame along the length direction and forms a second opening, through which the slide table slides into or out of the chute.

[0012] As an alternative to the conveyor belt assembly, the top of the slide table is also provided with a bearing seat, which extends out of the first opening and rotatably houses one end of the driven roller axially.

[0013] As an optional solution for the conveyor belt assembly, the slide table has a first hole, and the bottom wall of the chute has a second hole, the second hole extending along the length direction and communicating with the first hole; the locking member is sequentially inserted through the first hole and the second hole to lock or unlock the relative position of the slide table in the chute.

[0014] As an alternative to the conveyor belt assembly, the conveyor frame is provided with scale lines along the length direction, and the scale lines are located on one side of the chute.

[0015] As an alternative to the conveyor belt assembly, the conveyor belt assembly further includes a connecting rod, the two ends of which are detachably connected to the corresponding slides.

[0016] As an alternative to the conveyor belt assembly, the link is provided with a handle.

[0017] The hoist includes a hoisting frame and the aforementioned conveyor belt assembly, wherein the conveyor frame is mounted on the hoisting frame.

[0018] The beneficial effects of this utility model are as follows:

[0019] The conveyor belt assembly proposed in this utility model allows for rapid adjustment of the conveyor belt tension when the belt tension needs to be adjusted. The locking mechanism unlocks the slide, which then moves along its length on the conveyor frame to adjust its relative position, maintaining the belt tension. The locking mechanism then locks the slide back onto the conveyor frame, enabling quick adjustment of the conveyor belt tension. This conveyor belt tension adjustment operation is simple, shortens adjustment time, and improves the efficiency of tension adjustment.

[0020] The lifting machine proposed in this utility model includes the aforementioned conveyor belt assembly. When it is necessary to adjust the tension of the conveyor belt, the locking member unlocks the slide, and the slide moves along the length direction on the conveyor frame to adjust the relative position of the slide with respect to the conveyor frame, so that the conveyor belt remains taut. Then, the locking member locks the slide in place on the conveyor frame, realizing rapid adjustment of the conveyor belt tension. The above-mentioned conveyor belt tension adjustment operation is simple, shortens the adjustment time, and improves the efficiency of conveyor belt tension adjustment. Attached Figure Description

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 and Figure 2 As shown in the figure, this embodiment proposes a hoist, which includes a hoisting frame 8 and a conveyor belt assembly. The conveyor belt assembly includes a conveyor frame 1, a drive roller 2, a driven roller 3, a driving member 4, and a conveyor belt 5. The drive roller 2 and the driven roller 3 are spaced apart on the conveyor frame 1 along the length direction (front and back direction in the figure). The conveyor belt 5 is sleeved on the drive roller 2 and the driven roller 3. The driving member 4 is connected to the drive roller 2 in a transmission manner.

[0033] Specifically, the drive component 4 is a rotary motor. Rotary motors have a simple structure and high control precision, and can adapt to complex working environments. The output end of the drive component 4 is connected to one end of the drive roller 2 to drive the drive roller 2 to rotate on the conveyor frame 1. The drive roller 2 drives the driven roller 3 to rotate synchronously through the conveyor belt 5, so that the conveyor belt 5 transports materials. In this embodiment, the conveyor frame 1 is installed on the lifting frame 8. The conveyor frame 1 is inclined on the lifting frame 8 along the height direction (up and down direction in the figure) to transport materials from a lower position to a higher position through the conveyor belt 5, realizing vertical or inclined material conveying.

[0034] After the existing elevator is installed, the installation positions of the drive roller and the driven roller are fixed. When adjusting the tension of the conveyor belt, the drive roller and the driven roller must be removed and a new conveyor belt must be replaced to ensure the tension effect of the conveyor belt. This consumes a lot of manpower and replacement time, and reduces the efficiency of conveyor belt tension adjustment.

[0035] To solve the above problems, such as Figure 1 and Figure 2 As shown, the conveyor belt assembly in this embodiment also includes two adjustment components. Each adjustment component includes a slide table 6 and a locking member 7. The slide tables 6 of the two adjustment components are spaced apart on the conveyor frame 1 along the width direction (left-right direction in the figure). The two ends of the driven roller 3 are rotatably mounted on their respective slide tables 6 along the axial direction. The position of the slide tables 6 is adjustable along the length direction. The locking member 7 is configured to lock or unlock the relative position of the slide tables 6 and the conveyor frame 1. When it is necessary to adjust the tension of the conveyor belt 5, the locking member 7 unlocks the slide tables 6, and the slide tables 6 move along the length direction on the conveyor frame 1 to adjust the relative position of the slide tables 6 with respect to the conveyor frame 1, so that the conveyor belt 5 remains taut. Then, the locking member 7 locks the slide tables 6 to the conveyor frame 1, realizing rapid adjustment of the tension of the conveyor belt 5. The above-described tension adjustment operation of the conveyor belt 5 is simple, shortens the adjustment time, and improves the tension adjustment efficiency of the conveyor belt 5.

[0036] In this embodiment, the axial direction of the driven roller 3 is the same as the width direction of the conveyor frame 1. Two slides 6 are spaced apart along the width direction of the conveyor frame 1 and located on the left and right sides of the driven roller 3. The left end of the driven roller 3 is rotatably mounted on the left slide 6, and the right end of the driven roller 3 is rotatably mounted on the right slide 6. When it is necessary to adjust the tension of the conveyor belt 5, the two slides 6 move synchronously along the length direction of the conveyor frame 1 to flexibly adjust the distance between the driving roller 2 and the driven roller 3, and to ensure that the axial directions of the driven roller 3 and the driving roller 2 remain parallel during the adjustment process, thus preventing the driven roller 3 from shifting position.

[0037] like Figure 2 and Figure 3 As shown, the conveyor frame 1 has a slide groove 11 along its length, and each slide table 6 is slidably disposed within the corresponding slide groove 11. A locking element 7 locks or unlocks the slide table 6 within the slide groove 11. Slide grooves 11 are provided on both the left and right sides of the conveyor frame 1, with each slide table 6 corresponding to a slide groove 11 for sliding engagement. This allows the slide table 6 to be limited laterally along its length by the slide groove 11, improving the stability and reliability of the slide table 6's movement during position adjustment. When the slide table 6 slides into position within the slide groove 11, the locking element 7 locks the slide table 6 in its position within the slide groove 11 to ensure the stability of the slide table 6's position, thus maintaining a fixed distance between the driving roller 2 and the driven roller 3, thereby keeping the conveyor belt 5 taut.

[0038] In an optional embodiment, pressure plates 12 are provided on the top ends of both sides of the slide 11 along the width direction, forming a first opening 111 between the two pressure plates 12, so that the longitudinal section of the slide 11 is an inverted T-shape. Two stepped surfaces 61 are provided at intervals on the top end of the slide table 6. When the slide table 6 slides on the slide 11, the two pressure plates 12 overlap the corresponding stepped surfaces 61. The two pressure plates 12 and the bottom wall of the slide 11 provide vertical and horizontal limits for the slide table 6, further improving the stability and reliability of the slide table 6 during position adjustment. By setting the slide 11 as an inverted T-shaped groove, guiding and limiting the slide table 6 in two directions (width and height) is achieved, enabling the slide table 6 to slide stably along the length of the conveyor frame 1, thus improving the position adjustment accuracy of the slide table 6.

[0039] It should be noted that, as Figure 2 As shown, a bearing seat 62 is also provided at the top of the slide table 6. The bearing seat 62 extends out of the first opening 111 and is rotatably connected to one end of the driven roller 3. The first opening 111 is used to avoid the bearing seat 62 of the slide table 6, so that the bearing seat 62 protrudes from the first opening 111 into the groove 11 and is rotatably connected to the driven roller 3 to achieve stable support for the driven roller 3.

[0040] like Figure 2 and Figure 3 As shown, one end of the chute 11 extends through the conveyor frame 1 along its length and forms a second opening 112. The slide table 6 slides into or out of the chute 11 through the second opening 112. Since the chute 11 is an inverted T-shaped groove, the slide table 6 can slide into or out of the chute 11 through the second opening 112, realizing the quick assembly and disassembly of the slide table 6 on the conveyor frame 1, which facilitates the replacement and maintenance of the slide table 6.

[0041] like Figure 3 and Figure 4 As shown, the slide table 6 has a first hole 63, and the bottom wall of the slide groove 11 has a second hole 113, which extends along the length direction and communicates with the first hole 63. Locking members 7 are sequentially inserted through the first hole 63 and the second hole 113 to lock or unlock the relative position of the slide table 6 within the slide groove 11. Specifically, the locking members 7 are bolts and nuts, and the second hole 113 is an oblong hole. When the slide table 6 slides within the slide groove 11, the first hole 63 remains in communication with the second hole 113. When the slide table 6 slides into position, the bolt passes through the first hole 63 and the second hole 113 sequentially and locks with the nut, thus securing the slide table 6 within the slide groove 11. When the position of the slide table 6 needs to be adjusted, simply remove the bolt and nut, making the position adjustment operation of the slide table 6 simple and easy, and improving the tension adjustment efficiency of the conveyor belt 5.

[0042] In an optional embodiment, the conveyor frame 1 is provided with scale lines (not shown in the figure) along its length, and the scale lines are located on one side of the slide 11. Scale lines are engraved or pasted on one side of the first opening 111 at the top of each slide 11 along its length to quantify the position adjustment distance of the slide 6, improve the position adjustment accuracy of the slide 6, and achieve the same position adjustment distance for the two slides 6 without measurement, thereby improving the adjustment accuracy of the two slides 6 and preventing position deflection of the driven roller 3.

[0043] In an optional embodiment, the conveyor belt assembly further includes a connecting rod (not shown in the figure), with both ends of the connecting rod detachably connected to corresponding slides 6. When the slides 6 need to slide within the slide groove 11 for position adjustment, the two slides 6 are connected as one unit by the connecting rod, so that the two slides 6 slide synchronously along the length direction, thereby achieving synchronous position adjustment of the two slides 6. This avoids misalignment of the two slides 6 along the width direction of the conveyor frame 1, which would cause the driven roller 3 to shift position, thus improving the position adjustment accuracy of the slides 6.

[0044] Specifically, the connecting rod can be connected to the two slides 6 via a snap-fit ​​structure or screws. Once the slides 6 are adjusted to the correct position, the connecting rod can be easily removed, making the operation simple. In an optional embodiment, the connecting rod is equipped with a handle. By providing a handle on the connecting rod, the operator can easily pull or push the connecting rod along the length of the conveyor frame 1 to achieve synchronous position adjustment of the two slides 6.

[0045] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
