Description

Technical Field

[0001] The utility model relates to the field of grab buckets, in particular to a light single-rope grab bucket. Background Technique

[0002] During the sewage treatment process, after long-term operation, some equipment (such as the anaerobic tank of the biochemical system) will generate a large amount of sediment accumulated at the bottom of the equipment, which needs to be cleaned in time, otherwise it will affect the normal operation of the system. However, the bottom of some reaction tanks is relatively deep and often accompanied by a large amount of toxic and harmful gases, with extremely high danger, and personnel cannot enter the tank to clean the accumulated sediment.

[0003] The grab buckets at freight terminals on the market are relatively heavy in self-weight, with the minimum self-weight being about 3 tons. They use the self-weight of the grab bucket to grab materials into the bucket. However, this working method is extremely easy to damage the pool wall and bottom of the sewage treatment equipment, and the existing single-rope grab buckets do not have a protection function. Often, due to excessive rotation of the motor, the grab bucket closes excessively, resulting in damage to the equipment.

[0004] Therefore, we make improvements and propose a light single-rope grab bucket. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A light single-rope grab bucket of the utility model includes a driving component. A grab bucket boom is installed at the lower end of the driving component. An installation bottom block is fixedly installed at the lower end of the grab bucket boom. Grab bucket bodies are hingedly installed at both the left and right sides of the installation bottom block.

[0007] A detection block is slidably installed on the grab bucket boom in the vertical direction, and the upper end of the detection block is connected to the driving component. Two hinge rods are symmetrically hingedly installed at the upper ends of both grab bucket bodies. The other ends of the four hinge rods are symmetrically hingedly installed at the left and right ends of the detection block.

[0008] As a preferred technical solution of the utility model, the driving component includes an installation top plate. The installation top plate is fixedly installed at the upper end of the grab bucket boom. A driving motor is fixedly installed at the upper end of the installation top plate. The left end of the output shaft of the driving motor is connected to the upper end of the detection block through a driving box mechanism.

[0009] As a preferred technical solution of the present utility model, the driving box assembly includes a driving box. Inside the driving box, a horizontally arranged first rope winding shaft and a second rope winding shaft are rotatably installed. The left end of the output shaft of the driving motor penetrates through the driving box, and the first rope winding shaft and the second rope winding shaft are symmetrically arranged on the front and rear sides of the output shaft of the driving motor. A first single-rope winding drum and a second single-rope winding drum are respectively fixedly sleeved on the first rope winding shaft and the second rope winding shaft. A first single rope and a second single rope are respectively wound on the first single-rope winding drum and the second single-rope winding drum. The lower ends of the first single rope and the second single rope both penetrate through the driving box and the installation top plate, and are symmetrically and fixedly installed on the upper end of the detection block.

[0010] The output shaft of the driving motor is mechanically linked to the first rope winding shaft and the second rope winding shaft. The left end of the output shaft of the driving motor penetrates through the driving box and is rotatably connected to a fixed side plate, and the fixed side plate is fixedly installed on the upper end surface of the installation top plate.

[0011] As a preferred technical solution of the present utility model, gears are respectively fixedly sleeved on the output shaft of the driving motor and the first rope winding shaft, and the two gears are meshed with each other.

[0012] As a preferred technical solution of the present utility model, transmission wheels are respectively fixedly sleeved on the output shaft of the driving motor and the second rope winding shaft, and the two transmission wheels are connected by a transmission belt.

[0013] As a preferred technical solution of the present utility model, a distance sensor is fixedly installed on the lower end surface of the installation top plate, and the sensing end of the distance sensor is located directly above the detection block. A controller is fixedly installed on the upper end surface of the installation top plate.

[0014] As a preferred technical solution of the present utility model, the distance sensor is electrically connected to the controller, and the controller is electrically connected to the driving motor.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. For this kind of light single-rope grab, the output shaft of the driving motor drives the first rope winding shaft and the second rope winding shaft to rotate. The rotating first rope winding shaft and the second rope winding shaft can drive the first single-rope winding drum and the second winding drum to rotate. The rotating first winding drum and the second winding drum can wind the first single rope and the second single rope, thereby driving the detection block to move upward. The upward movement of the detection block can drive the two grab bodies to automatically close through the articulated pull rod.

[0017] 2. This type of light single-rope grab sets a minimum value for the controller. The distance sensor can collect the distance information between the detection blocks directly below it and transmit it to the controller. The controller converts the distance information into data. When the detection block moves up to the point where the two grab bodies are completely closed, the data is equal to the minimum value. The controller can then send a command to the drive motor, which will automatically shut down, thereby preventing the drive motor from over-rotating and causing damage to the equipment.

[0018] The utility model has a self-protection function, which effectively avoids the problem that the driving motor rotates excessively and thus causes damage to the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Example: Figures 1-3As shown in the figure, a light single-rope grab of the present utility model includes a driving assembly 1. A grab boom 2 is installed at the lower end of the driving assembly 1. An installation base block 6 is fixedly installed at the lower end of the grab boom 2. Grab bodies 5 are hingedly installed at both the left and right sides of the installation base block 6.

[0028] A detection block 3 is slidably installed on the grab boom 2 in the vertical direction, and the upper end of the detection block 3 is connected to the driving assembly 1. Two articulated pull rods 4 are symmetrically hingedly installed at the upper ends of both grab bodies 5. The other ends of the four articulated pull rods 4 are symmetrically hingedly installed at the left and right ends of the detection block 3.

[0029] The driving assembly 1 can drive the detection block 3. When the detection block 3 moves upward, it can drive the two grab bodies 5 to automatically close through the articulated pull rods 4.

[0030] In this embodiment, as Figures 1-2 shown, the driving assembly 1 includes an installation top plate 101. The installation top plate 101 is fixedly installed at the upper end of the grab boom 2. A driving motor 102 is fixedly installed at the upper end of the installation top plate 101. The left end of the output shaft of the driving motor 102 is connected to the upper end of the detection block 3 through a driving box mechanism 103.

[0031] The driving box mechanism 103 includes a driving box 1035. A horizontally arranged first rope winding shaft 1031 and a second rope winding shaft 1039 are rotatably installed inside the driving box 1035. The left end of the output shaft of the driving motor 102 penetrates through the driving box 1035, and the first rope winding shaft 1031 and the second rope winding shaft 1039 are symmetrically arranged on the front and rear sides of the output shaft of the driving motor 102. A first single-rope winding drum 1034 and a second single-rope winding drum 1038 are respectively fixedly sleeved on the first rope winding shaft 1031 and the second rope winding shaft 1039. A first single rope 1033 and a second single rope 1037 are respectively wound on the first single-rope winding drum 1034 and the second single-rope winding drum 1038. The lower ends of the first single rope 1033 and the second single rope 1037 both penetrate through the driving box 1035 and the installation top plate 101, and are symmetrically fixedly installed at the upper end of the detection block 3.

[0032] The output shaft of the driving motor 102 is mechanically linked to the first rope winding shaft 1031 and the second rope winding shaft 1039. The left end of the output shaft of the driving motor 102 penetrates through the driving box 1035 and is rotatably connected to a fixed side plate 105. The fixed side plate 105 is fixedly installed on the upper end surface of the installation top plate 101.

[0033] The output shaft of the driving motor 102 drives the first rope winding shaft 1031 and the second rope winding shaft 1039 to rotate. The rotating first rope winding shaft 1031 and the second rope winding shaft 1039 can drive the first single-rope winding drum 1034 and the second winding drum to rotate. The rotating first winding drum and the second winding drum can wind the first single rope 1033 and the second single rope 1037, thereby driving the detection block 3 to move upward.

A transmission wheel is fixedly sleeved on both the output shaft of the driving motor 102 and the second winding shaft 1039, and the two transmission wheels are connected by a transmission belt 1036.

[0035] When the driving motor 102 is started, the driving motor 102 can drive the first winding shaft 1031 to rotate through the two gears 1032, and the driving motor 102 can drive the second winding shaft 1039 to rotate through the two transmission wheels and the transmission belt 1036.

[0036] A distance sensor 105 is fixedly installed on the lower end surface of the installation top plate 101, and the sensing end of the distance sensor 105 is located directly above the detection block 3. A controller 104 is fixedly installed on the upper end surface of the installation top plate 101. The distance sensor 105 is electrically connected to the controller 104, and the controller 104 is electrically connected to the driving motor 102.

[0037] The controller 104 is a SC200 general-purpose controller, and a minimum value is set for the controller 104. The distance sensor 105 can collect the distance information between the detection block 3 directly below it and transmit it to the controller 104. The controller 104 converts the distance information into data. When the detection block 3 moves up to the point where the two grab bodies 5 are completely closed, this data is equal to the minimum value, and the controller 104 can send an instruction to the driving motor 102, and the driving motor 102 can automatically shut down.
