Description
Technical field:
[0001] The utility model belongs to the technical field of dust collecting hoods, and more particularly relates to an adjustable dust collecting hood. Background technology:
[0002] With the rapid development of science and technology, chemical, building materials, plastic and other production enterprises have sprung up and flourished. In the production of chemical, building materials and plastic processing, the requirements for equipment automation and environmental protection are getting higher and higher. The dust hoods currently used are generally made of metal plates and placed above the dust removal site. Many factories use fixed dust hoods for smoke collection, which has the advantages of low cost and high capture rate.
[0003] However, for some large workpieces that need to be lifted by a gantry crane, a fixed dust hood cannot be used. Due to site limitations, it is difficult to cover the entire workpiece. If the workpiece is too large, it will be difficult to process, the use site will be limited, and it will be difficult to move, and the dust collection and removal functions cannot be truly exerted. Since the specifications and sizes of the workpieces to be processed are different, the distance between the dust hood and the workpieces to be processed is also different. If the distance is too far, the motor power and suction need to be increased, which will consume more electricity, not only increasing the power consumption, but also the noise removal, smoke removal and dust collection effects are poor. Dust and noise pollution in the production environment cannot be controlled, seriously affecting people's health and living environment. Utility model content:
[0004] In order to solve the above problems and overcome the shortcomings of the prior art, the utility model provides an adjustable dust hood;
[0005] The first technical problem to be solved is that the factory workshop space is limited and cannot meet the dust collection needs of workpieces of different specifications and sizes at the same time, which increases electricity consumption. In addition, the noise removal, smoke removal and dust collection effects are poor. Dust and noise pollution in the production environment cannot be controlled, which seriously affects people's health and living environment.
[0006] The specific technical solution of the utility model to solve the above technical problems is as follows: the adjustable dust hood comprises a support frame and a mounting frame, the mounting frame is horizontally arranged on the inner side of the support frame, and the dust hood is arranged below the mounting frame;
[0007] The mounting frame is provided with a lifting structure for adjusting the height of the dust collecting hood and a transverse driving device for adjusting the horizontal position of the dust collecting hood;
[0008] The lifting structure includes a lifting frame fixedly connected to the mounting frame and a driving assembly that drives the lifting frame to reciprocate along the vertical direction of the support frame. The lifting frame is fixedly arranged on an end of the mounting frame away from the dust collecting hood. Stabilizing wheels are arranged on the outer wall of the lifting frame through a rotating shaft. The stabilizing wheels are symmetrically arranged on both sides of the lifting frame. A vertical slide groove adapted for the stabilizing wheel is opened on the inner wall of the support frame, and the stabilizing wheel is rollingly arranged in the vertical slide groove.
[0009] Furthermore, the stabilizing wheel is divided into a front stabilizing wheel and a rear stabilizing wheel. The front stabilizing wheel is arranged at an upper position of the side wall of the lifting frame and contacts the front end surface of the vertical slide groove; the rear stabilizing wheel is arranged at a lower position of the side wall of the lifting frame and contacts the rear end surface of the vertical slide groove.
[0010] Furthermore, the ball screw passes through the lifting frame and is matched with the lifting frame through threads. The inner wall of the lifting frame is provided with an internal thread that is compatible with the external thread of the ball screw.
[0011] Furthermore, the drive assembly includes a ball screw and a reduction motor. The ball screw is arranged inside the support frame along the central axis of the support frame, and both ends are rotatably connected to the support frame through bearings. One end of the ball screw passes through the upper end surface of the support frame and extends to the outside to be key-connected to the reduction motor.
[0012] Furthermore, the lateral drive device includes a driving cylinder for driving the dust hood to move laterally along the mounting frame. The driving cylinder is mounted on the mounting frame through a mounting plate. The output end of the driving cylinder is fixedly connected to a fixed seat. The fixed seat is fixedly set at the upper end of the dust hood. The dust hood is slidably connected to the mounting frame.
[0013] Furthermore, a preset number of transverse pulleys are symmetrically arranged on both sides of the dust collecting hood, and a transverse sliding groove adapted to the transverse pulley is provided at the inner wall of the mounting frame, and the transverse pulley is arranged in the transverse sliding groove.
[0014] Furthermore, an air outlet is provided on the upper end surface of the dust collecting hood, and an air suction hose is detachably connected to the outer side of the air outlet through a clamp.
[0015] The beneficial effects of the utility model are:
[0016] One advantage of the present invention is that a lifting structure for adjusting the horizontal height of the dust hood and a transverse driving device for adjusting the horizontal position of the dust hood are provided on the mounting frame. The transverse position of the dust hood body is adjusted by the transverse driving device, and the height is adjusted up and down by the lifting structure. Thus, the distance between the dust hood body and the dust source can be adjusted according to the different specifications of the workpiece to be processed, thereby improving the noise removal, smoke removal and dust collection effects, and reducing the overflow of pollutants such as dust and power consumption.
[0017] One advantage of the present invention is that a front stabilizing wheel and a rear stabilizing wheel are provided on the outer side wall of the lifting frame through a rotating shaft.

Specific implementation method:
[0021] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "left," "right," "rear," "lower left," "upper right," and "outer" and the like, indicating positions or locations, are based on the positions or locations shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] Specific implementation of the utility model: The adjustable dust hood comprises a support frame 1 and a mounting frame 2, wherein the mounting frame 2 is horizontally arranged inside the support frame 1, a dust hood body 3 is arranged below the mounting frame 2, an air outlet 31 is opened on the upper end surface of the dust hood body 3, and an air suction hose is detachably connected to the outer side of the air outlet 31 through a clamp;
[0023] In order to meet the dust collection requirements of workpieces of different specifications and sizes in a limited space and prevent dust from overflowing, the following improvements are made to the present invention:
[0024] The mounting frame 2 is provided with a lifting structure 4 for adjusting the height of the dust hood body 3 and a transverse driving device 5 for adjusting the horizontal position of the dust hood body 3;
[0025] The mounting frame 2 is slidably connected to the support frame 1 through a lifting structure 4, and slides up and down along the support frame 1 to adjust the horizontal height of the dust hood body 3; preferably, the lifting structure 4 includes a lifting frame 41 fixedly connected to the mounting frame 2 and a driving assembly 42 that drives the lifting frame 41 to reciprocate in the vertical direction along the support frame 1;
[0026] The lifting frame 41 is fixedly set on the end of the mounting frame 2 away from the dust collecting hood body 3, and a stabilizing wheel is set on the outer wall of the lifting frame 41 through a rotating shaft. The stabilizing wheels are symmetrically arranged on both sides of the lifting frame 41, and a vertical slide groove 11 adapted for the stabilizing wheel is opened on the inner wall of the support frame 1, and the stabilizing wheel is rollingly set in the vertical slide groove 11.
[0027] With this design, the dust hood body 3 can adjust its horizontal position through the lateral drive device 5, and can adjust its height up and down through the lifting structure 4, so that the distance between the dust hood body 3 and the dust source can be adjusted according to the different specifications of the workpiece to be processed, thereby improving the noise removal, smoke removal and dust collection effects, and reducing the overflow of pollutants such as dust and power consumption.
[0028] During operation, the dust hood body 3 continuously applies a downward force to the mounting bracket 2. Since the dust hood body 3 is supported by a single support arm, the longer the dust hood body 3 is extended, the greater the force applied. Long-term use causes the screw rod to be damaged by long-term stress concentration, and the position of the mounting bracket 2 deviates, thereby affecting the dust collection effect. Preferably, the stabilizing wheel is divided into a front stabilizing wheel 411 and a rear stabilizing wheel 412. The front stabilizing wheel 411 and the rear stabilizing wheel 412 have the same structure, and the difference is only in the different installation positions; the front stabilizing wheel 411 is arranged on the upper side wall of the lifting frame 41 and contacts the front end surface of the vertical slide groove 11; the rear stabilizing wheel 4 12 is arranged at the lower position of the side wall of the lifting frame 41 and is in contact with the rear end surface of the vertical slide groove 11; with this design, the front stabilizing wheel 411 and the rear stabilizing wheel 412 cooperate with each other in the vertical slide groove 11. When the dust collecting hood body 3 applies a downward force to the mounting frame 2, the front stabilizing wheel 411 and the rear stabilizing wheel 412 can respectively fit tightly with the front and rear end surfaces in the vertical slide groove 11. On the one hand, it can ensure that the lifting frame 41 moves smoothly along the support frame 1, and can also be used to assist in supporting the mounting frame 2 to prevent the screw rod from being damaged by long-term stress concentration, and the vertical slide groove 11 can also limit the stabilizing wheel to prevent the position of the mounting frame 2 from deviating and affecting the dust collection effect.
[0029] Preferably, the driving assembly 42 includes a ball screw 421 and a reduction motor 422. The ball screw 421 passes through the lifting frame 41 and is threadedly matched with the lifting frame 41. The inner wall of the lifting frame 41 is provided with an internal thread that matches the external thread of the ball screw; the ball screw 421 is arranged inside the support frame 1 along the central axis of the support frame 1, and its two ends are rotatably connected to the support frame 1 through bearings. One end of the ball screw 421 passes through the upper end surface of the support frame 1 and extends to the outside to be key-connected with the reduction motor 422. The reduction motor 422 is fixedly set at the upper end of the support frame 1.
[0030] Preferably, the transverse drive device 5 includes a driving cylinder 51 for driving the dust hood body 3 to move laterally along the mounting frame 2. The driving cylinder 51 is mounted on the mounting frame 2 through a mounting plate 52. The output end of the driving cylinder 51 is fixedly connected to a fixed seat 32. The fixed seat 32 is fixedly set at the upper end of the dust hood body 3. The dust hood body 3 is slidingly connected to the mounting frame 2. A preset number of transverse pulleys 33 are symmetrically arranged on both sides of the dust hood body 3. A transverse groove 21 adapted to the transverse pulley 33 is provided on the inner wall of the mounting frame 2. The transverse pulley 33 is arranged in the transverse groove 21.
[0031] It should be noted that the present invention is an adjustable dust hood. During operation, the workpiece to be processed is manually hoisted to the bottom of the dust hood body 3 using a hoisting tool. Due to manual hoisting, the position will deviate. The driving cylinder 51 is manually opened to adjust the lateral direction of the dust hood body 3. The output end of the driving cylinder 51 drives the fixed seat 32 to move, and the fixed seat 32 drives the dust hood body 3 to move. The transverse pulleys 33 on both sides of the dust hood body 3 move in the transverse slide grooves 21, driving the dust hood body 3 to move along the mounting frame 2, thereby adjusting the lateral position of the dust hood body 3.
[0032] After the lateral position of the dust hood body 3 is determined, the horizontal height of the dust hood body 3 is manually adjusted up and down through the driving component 42, and the reduction motor 422 is turned on. The output shaft of the reduction motor 422 transmits power to the ball screw 421, driving the ball screw 421 to rotate, and the stabilizing wheels on both sides of the lifting frame 41 move along the vertical slide groove 11 under the threaded transmission of the ball screw 421, thereby adjusting the horizontal height of the dust hood body 3, and the lifting frame 41 is adjusted up and down by adjusting the forward and reverse rotation of the reduction motor 422, wherein the reduction motor 422 is a forward and reverse motor, and the reciprocating motion of the lifting frame 41 can be achieved by changing the forward and reverse rotation of the reduction motor 422; as is well known to those skilled in the art, forward and reverse motors are commonplace and belong to conventional means or common sense, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.
[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
