DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments, and the following embodiments do not limit the invention involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solutions of the invention.

[0022] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments. Example

[0023] like Figure 1, 2 As shown, a construction material transfer device includes a sealing cylinder and a lifting device for lifting the sealing cylinder 13, the lifting device is, for example, a crane, the sealing cylinder has an openable bottom cover, a material grabbing mechanism is arranged in the sealing cylinder, the side wall of the sealing cylinder is connected to the air supply device 14 through a pipeline, and the top of the sealing cylinder is connected to the exhaust device 15 through a pipeline, the air supply device can be a hair dryer, and the exhaust device can be an exhaust fan and a dust bag 16. When in use, the sealing cylinder is lifted above the material, the bottom cover is opened, the material is grabbed into the sealing cylinder by the grabbing mechanism, and then the bottom cover is closed. While lifting the sealing cylinder, the air supply device blows air into the sealing cylinder to blow off the dust or pollutants on the material, and the exhaust device sucks these pollutants into the dust bag for storage. When the material is transported to the required position, the air supply device and the exhaust device stop working, and after the sealing cylinder is lowered to a suitable position, the bottom cover opens the grabbing mechanism to put the material into a suitable position, thereby preventing the pollutants from being transferred along with the material, making the surface of the material clean and preventing the pollutants from spreading.

[0024] Furthermore, the sealing cylinder side wall is provided with an air inlet connected to the air supply device, and the air inlet is tangent to the sealing cylinder side wall, so that the wind enters the sealing cylinder along the sealing cylinder side wall in a spiral manner, so that the sealing cylinder is blown by air without dead corners.

[0025] The lower end of the sealing cylinder is provided with a support frame 17 extending downwards, and the length of the support frame relative to the lower end of the sealing cylinder is greater than the length of the end cover after opening downwards, so that when the sealing cylinder is supported on the ground or other objects by the support frame, it is convenient for the end cover to be opened, and it is convenient for the grabbing mechanism to extend from the lower end of the sealing cylinder to grab the material.

[0026] like Figure 3 , 4As shown in Figure 5, the grabbing mechanism includes a first grabbing component, the first grabbing component includes a first jaw, a second jaw and a traction rope 1 connected to the lifting device, the first jaw and the middle part of the second jaw are rotatably connected through a hinge shaft 2, the two ends of the first jaw and the second jaw are respectively the first end and the second end, the first end of the first jaw and the second jaw is provided with a first clamping part, the first clamping part is a bending part relative to the inner side of the grabbing mechanism, the second end of the first jaw is connected to the traction rope, the second end of the second jaw is provided with a second guide part, the traction rope slides around the guide part to pull the grabbing mechanism upward. Pull the traction rope upward, the traction rope makes the second ends of the first clamp and the second clamp approach each other, so that the first clamping part 9 of the second end of the first clamp and the second clamp approaches each other to clamp the material, and the friction force generated by the material and the first clamping part is balanced with gravity to keep the object stable, and then use a crane or other device to pull the traction rope to lift the material 12 to the required place. After lifting it to the place where it needs to be placed, the traction rope is lowered, so that the material is lowered and placed where it needs to be placed, and the traction rope continues to be pulled below. Under the action of gravity, the second ends of the first clamp and the second clamp move away from each other, so that the grabbing mechanism opens, and then the worker can take away the material, and the grabbing mechanism grabs the next material.

[0027] Furthermore, it also includes a second grasping assembly, the second grasping assembly includes a third jaw and a fourth jaw, the middle parts of the third jaw and the fourth jaw are rotatably connected by a hinge shaft, the two ends of the third jaw and the fourth jaw are respectively a first end and a second end, the first end of the third jaw and the fourth jaw is provided with a second clamping portion, the second end of the third jaw and the fourth jaw is respectively provided with a third guide portion and a fourth guide portion, and the traction rope slides around the third guide portion and the fourth guide portion to pull the grasping mechanism upward. In this way, when the traction rope is pulled upward, the first jaw and the second jaw, and the third jaw and the fourth jaw can be closed to grasp the material, and because the first grasping assembly and the second grasping assembly are pulled by the same traction rope, even if one of the grasping assemblies cannot continue to close, the other grasping assembly can continue to close without affecting each other, so that the two grasping assemblies grasp different parts of the material, which is suitable for grasping complex material shapes.

[0028] Further, the third clamp and the fourth clamp are a gate-shaped frame, the gate-shaped frame includes two parallel outer vertical rods 3, the lower end of the vertical rod is the second clamping part 4, the upper ends of the two outer vertical rods are connected by an upper connecting rod 5, and the upper connecting rod is the guide part. The upper connecting rods of the second clamp, the third clamp and the fourth clamp are provided with a guide wheel 6 for guiding the traction rope. The first clamp and the second clamp are located between the two parallel outer vertical rods. The first clamp and the second clamp are a frame structure, the frame structure includes two parallel inner vertical rods 7, the lower ends of the two inner vertical rods are connected by the first clamping part, the upper ends of the two inner vertical rods are connected by a lower connecting rod 8, the lower connecting rod of the second clamp is the guide part, and the traction rope is connected to the lower connecting rod of the first clamp. In this way, the first grasping assembly is located inside the second grasping assembly, the first grasping assembly is used to grasp the middle part of the object, and the second grasping assembly is used to grasp the two ends of the object.

[0029] The hinge shaft is connected with a bracket 10 located between the first clamping jaw and the second clamping jaw, and the bracket is provided with a traction rope guide 11 located above the grabbing mechanism. The guide comprises two guide wheels, and the traction rope slides through between the two guide wheels, thereby providing a guide for the traction rope.

[0030] The end cover includes a first cover plate 18 and a second cover plate 19 that are opened apart. The first cover plate and the second cover plate are both rotatably connected to the lower port of the sealing cylinder through an axial hinge. A reset spring 20 is connected between the first cover plate, the second cover plate and the outer wall of the sealing cylinder. The tension of the reset spring can make the first cover plate and the second cover plate open to both sides relative to the lower port of the sealing cylinder. The inner sides of the first cover plate and the second cover plate are connected to the two ends of the hinge axis through pull ropes 23 respectively.

[0031] The traction rope slides through the upper end of the sealing cylinder, and the side wall of the sealing cylinder is provided with two opposite sliding grooves 21 in the upper and lower directions. The two ends of the hinge shaft slide in the sliding grooves, and the upper end of the sliding groove has a locking portion 22 for locking the hinge shaft. When the hinge shaft is locked to the locking portion, the first cover plate and the second cover plate cover the lower port of the sealing cylinder.

[0032] When the support frame is supported around the material, the traction rope is lowered, so that the grabbing mechanism moves downward, and due to the downward movement of the hinge shaft, the pull rope moves downward and loses the pulling force on the end cover, at this time the return spring contracts so that the pull rope, the first cover plate and the second cover plate rotate toward the outside of the port, thereby opening the lower port; then the grabbing mechanism continues to descend to the material, and then pulls the traction rope upward, so that the grabbing mechanism grabs the material and then moves upward, when the hinge shaft is locked to the locking portion, the first cover plate and the second cover plate cover the lower port of the sealing cylinder, and the traction rope continues to move upward, thereby the sealing cylinder is pulled upward at the same time through the locking of the hinge shaft to the locking portion. When the sealing cylinder moves to the position where the material needs to be placed, the traction rope is lowered, causing the grabbing mechanism to move downward. As the hinge shaft moves downward, the pull rope moves downward and loses the pulling force on the end cover. At this time, the return spring contracts, causing the pull rope, the first cover plate and the second cover plate to rotate toward the outside of the port, thereby opening the lower port; then the grabbing mechanism continues to descend to lower the material to the ground or other position where it needs to be placed.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them in similar ways, without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0034] Although some terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention. The execution order of actions, steps, etc. in the devices and methods shown in the specification and the drawings can be implemented in any order as long as there is no special explicit limitation on the order and the output of the previous processing is not used in the subsequent processing. Similar sequential terms (for example, "first", "next", "secondly", "again", "then", etc.) used for the convenience of description do not mean that they must be implemented in such an order.

[0035] It should be understood by those skilled in the art that all directional references (e.g., above, below, upward, up, downward, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to facilitate the reader's understanding, and do not represent limitations (e.g., on position, orientation or use, etc.) on the scope of the invention as defined by the appended claims. They are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation. The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0036] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0037] In addition, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or slight deviations of conditions, quantities, values, or dimensions, some of which are within the manufacturing deviation or tolerance range. It should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meanings and therefore cannot be understood as limiting the scope of protection of this application.
