Description

Technical Field

[0001] The utility model relates to the field of container lifting, in particular to a reach stacker with a spraying device. Background Art

[0002] In the process of handling bulk materials at ports and logistics centers, traditional lifting equipment needs to lift and rotate containers to dump the materials. During this process, a large amount of dust is easily generated and diffused from bulk materials (such as coal, grain, etc.), polluting the environment and endangering the health of operators. Moreover, due to the excessive suspended particulate matter in the air, there is also an explosion risk. In the prior art, some equipment attempts to suppress dust by attaching a spraying system, but there are still problems such as poor adaptability to low-temperature environments, insufficient adaptability of pipeline layout and telescoping, limited automation control level, low spraying coverage and dust suppression efficiency, etc. Content of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide a reach stacker with a spraying device to achieve the purpose of reducing the amount of dust generated when dumping bulk materials.

[0006] A spreader for connecting and fixing with a container is arranged at one end of the boom. A nozzle connected to the pipeline mechanism and located at the side of the container is arranged on the spreader. The nozzle is configured to spray water outwards to reduce the dust around the container. The pipeline mechanism includes a reel member fixed on the boom and a first pipeline partially wound on the reel member and extending and retracting along with the boom.

[0007] Furthermore, at least one guide seat is further arranged on the boom, and the guide seat is configured to guide the first pipeline from the reel member.

[0008] Furthermore, the first pipeline is a self-heating pipeline.

[0009] Furthermore, a water supply mechanism connected to the pipeline mechanism is further included.

[0010] Furthermore, the water supply mechanism has a water tank fixed on the vehicle body, and the water tank is connected to the pipeline mechanism through a second pipeline.

[0011] Furthermore, a liquid level sensing mechanism is arranged in the water tank.

[0012] Further, the water tank is connected to the second pipeline through a water pump.

[0013] Further, the second pipeline is a self-heating pipeline.

The terms "including", "comprising" and "containing" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0024] In the specification, when it is stated that an element is "on", "fixed" to, "connected" to, "joined" to another element, etc., the element can be directly on, fixed to, connected to, joined to or in contact with the other element, or there may be intermediate elements. In the specification, when a feature is arranged "adjacent" to another feature, it may mean that a feature has a part that overlaps with the adjacent feature or a part that is above or below the adjacent feature.

[0025] It can be understood that although terms such as "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the concept of the present application.

[0026] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals denote the same or functionally identical elements.

[0027] Figure 1 The overall structure of such a spray front gantry crane is shown, including a movable vehicle body 10 and a controllable telescopic boom 30 provided on the upper part of the vehicle body 10. A spreader 50 for connecting to and clamping and lifting a container 52 is provided at the front end of the boom 30.

[0028] The pipeline mechanism is placed on the boom 30 and is arranged to be able to extend and retract with the boom 30. The pipeline mechanism includes a reel member 42 fixed on the boom 30 and a first pipeline 44 extending from the reel member 42. A number of guide seats 45 are also fixed on the boom 30 to cooperate with the reel member 42 to guide the first pipeline 44 to extend along a predetermined route with the boom 30. A nozzle 46 is provided on the spreader 50, and the nozzle 46 is communicated with a water supply mechanism 41 through the pipeline mechanism to achieve spraying.

[0029] In one embodiment, the reel member 42 and the guide seats 45 are placed on the top of the boom 30, and the first pipeline 44 extends and travels along the upper part of the boom 30 with the guide seats 45.

[0030] Combined Figure 2 , the guide seat 45 is fixed to the boom 30 through a base 45a, a guide wheel 45b is located on the base 45a and can rotate freely, and a groove 45c matching the outer contour of the first pipeline 44 is formed on the outer periphery of the guide wheel 45b so that the first pipeline 44 is positioned through the groove 45c and moves with the rolling of the guide wheel 45b.

[0031] Combined reference Figure 3 Figure 3 , the reel member 42 is composed of a reel 42b and a driving machine 42a provided on the axial side of the reel 42b. The driving shaft of the driving machine 42a axially extends into the reel 42b to drive the reel 42b to rotate, thereby controlling the telescopic movement of the first pipeline 44.

[0032] The water supply mechanism 41 is composed of a water tank and a second pipeline 43 connecting the water tank and the reel member 42. A liquid level sensing mechanism for sensing the height of the water level and a water pump for pumping liquid from the water tank into the second pipeline 43 are integrated in the water tank.

[0033] In one embodiment, the water supply mechanism 41 is placed on the side of the vehicle body 10, preferably at the rear of the vehicle, so that it can be used as a configuration structure synchronously.

[0034] Combined reference Figure 4 Figure 4 , in one embodiment, the second pipeline 43 and the first pipeline 44 are self-heating pipelines with a heating layer 43b coated on the outer layer of the inner pipe 43a to prevent freezing in a low-temperature environment.

[0035] The spreader 50 has a rotating mechanism 51 that can rotate the container 52 around the long axis direction, so that the bulk materials (such as coal, grain, etc.) in the container 52 can be dumped out. During this process, large-scale dust will occur around the container 52. Therefore, a nozzle 46 connected to the first pipeline 44 is provided on the spreader 50. The nozzle 46 is placed on the side adjacent to the container 52 and sprays water mist outward when the container 52 is dumped to reduce dust.

[0036] In one embodiment, the nozzle 46 is placed on the upper side of the container 52 and is configured to spray water toward the side. Preferably, the nozzle 46 can be selected to be configured to spray water toward the front and rear sides in the short side direction of the container 52 at the same time. The nozzle 46 can also be fixed to the spreader 50 through a bracket.

[0037] Furthermore, a warning light 21 for indicating the working state of the system is also provided on the control room 20.

[0039] Step S1: Start the water pump;

[0040] Step S2: Detect the water level height of the water tank through the liquid level and liquid temperature sensor;

[0041] Step S2.1: Judge whether the water level height of the water tank is less than or equal to the set value;

[0042] Step S2.2: If it is less than or equal to the set value, alarm through the warning light 21;

[0043] Step S3: Determine whether the working temperature is less than or equal to the set value;
