Description

Technical Field

[0001] The utility model relates to the field of composite material bridge sleeper processing equipment, in particular to a telescopic dust removal cover used for composite material bridge sleeper processing. Background Art

[0002] Composite bridge sleepers primarily support rails, maintaining the geometric alignment of two or more rails, including gauge, level, height, and orientation, through interconnecting components. Composite bridge sleepers are installed on bridge longitudinal beams, requiring slotting and drilling.

[0003] Composite bridge sleepers are primarily processed using CNC saws, which generate large amounts of dust during the process, significantly impacting worker health. To address this dust problem, rooftop dust hoods are currently the most common solution. These hoods have the advantages of not interfering with processing and requiring no daily maintenance. However, these hoods require high installation heights, high airflow rates, and high investment costs. Furthermore, they only partially remove dust, resulting in ineffective dust collection. Therefore, there is an urgent need to develop a low-cost, high-performance retractable dust hood for composite bridge sleeper processing. Summary of the Invention

[0004] The purpose of the utility model is to provide a telescopic dust removal cover for processing composite material bridge sleepers, aiming to solve the problem of poor dust removal effect when processing composite material bridge sleepers.

[0005] The technical solution adopted by the utility model is: a telescopic dust removal hood for processing composite material bridge sleepers, comprising an upper cover, shaft seats are respectively installed on the left and right sides of the top surface of the upper cover, an optical axis is installed on the shaft seats, a dust removal pipe interface is provided in the middle of the top surface of the upper cover, linear guide rails are respectively provided in the middle of the left and right sides of the upper cover, a slider is installed on the linear guide rail, a lower cover is provided below the upper cover, the lower cover includes two side vertical plates, the side vertical plates are fixedly connected to the slider, a spring balancer is also provided on the upper left and right sides of the upper cover, the upper part of the spring balancer is connected to the optical axis, the spring balancer includes an adjustable telescopic spring, the adjustable telescopic spring extends from the bottom of the spring balancer and extends downward, and the end of the adjustable telescopic spring is connected to the slider.

[0006] A further technical solution of the present invention is that the upper portion of the upper cover is expanded so that the upper cover forms a structure that is narrow at the bottom and wide at the top. During the dust removal process, the dust speed is slowed down due to the increase in the volume of the upper portion of the dust removal cover, which can ensure that the dust does not fly with the saw blade.

[0007] A further technical solution of the present invention is that a roller is installed under the lower cover, and the dust removal cover moves along with the composite material bridge sleeper processing through the movement of the roller.

[0008] A further technical solution of the present invention is that the dust removal pipe interface is circular and has a height of 5 cm to 15 cm, which is convenient for connecting the dust removal hood with an external dust collector through the dust removal pipe.

[0009] A further technical solution of the present invention is that a rotary adjustment button is provided on the spring balancer to facilitate adjustment of the length of the adjustable telescopic spring.

[0010] The beneficial effect of the present invention is that due to the adoption of the above technical scheme, a telescopic dust removal hood for composite material bridge sleeper processing of the present invention can be retracted and extended through a spring balancer, so that the lower cover of the dust removal hood always remains on the surface of the composite material bridge sleeper, effectively ensuring the dust removal effect and preventing dust from flying everywhere. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 The utility model is a schematic structural diagram of a telescopic dust removal cover for processing composite material bridge sleepers. DETAILED DESCRIPTION

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Example:

[0014] like Figure 1 A telescopic dust removal hood for processing composite material bridge sleepers is shown, a telescopic dust removal hood for processing composite material bridge sleepers, including an upper cover 1, an axle seat 3 is respectively installed on the left and right sides of the top surface of the upper cover, an optical axis 4 is installed on the axle seat, a dust removal pipe interface 8 is provided in the middle of the top surface of the upper cover, a linear guide rail 6 is respectively provided in the middle of the left and right sides of the upper cover, a slider 7 is installed on the linear guide rail, a lower cover 2 is provided below the upper cover, the lower cover includes two side vertical plates 21, the side vertical plates 21 are fixedly connected to the slider 7, a spring balancer 5 is also provided on the upper left and right sides of the upper cover, the upper part of the spring balancer is connected to the optical axis 4, the spring balancer includes an adjustable telescopic spring 51, the adjustable telescopic spring 51 extends from the bottom of the spring balancer and extends downward, and the end of the adjustable telescopic spring 51 is connected to the slider.

[0015] Preferably, the upper portion of the upper cover is expanded so that the upper cover forms a structure that is narrow at the bottom and wide at the top. During the dust removal process, the dust speed is slowed down due to the increase in the volume of the upper portion of the dust removal cover, which can ensure that the dust does not fly with the saw blade.

[0016] Preferably, a roller is installed under the lower cover, and the dust removal cover moves along with the processing of the composite material bridge sleeper through the movement of the roller.

[0017] Preferably, the dust removal pipe interface is circular and has a height of 5 cm to 15 cm, which is convenient for connecting the dust removal hood to an external dust collector through the dust removal pipe.

[0018] Preferably, a rotary adjustment button 52 is provided on the spring balancer to facilitate adjustment of the length of the adjustable telescopic spring.

[0019] During use, assemble the dust hood and connect it to the dust collection pipe of the external dust collector. Connect the bottom of the spring balancer to the lower cover of the dust hood to ensure that the saw blade's cutting depth is 5mm when the lower cover is in a free state. After the adjustment is completed, set the parameters of the spring balancer. Adjust the height of the dust hood and place it on the surface of the composite bridge sleeper. During processing, as the saw blade cuts the product downward, the lower cover of the dust hood slides upward via a linear guide to achieve telescoping, ensuring that the lower cover of the dust hood is always flush with the surface of the composite sleeper during processing. Dust generated during processing enters the interior of the upper cover of the dust hood. Since the upper cover of the dust hood has an expanded shape that is wider at the top and narrower at the bottom, the dust enters the interior of the upper cover of the dust hood. Due to the increased volume, the dust's speed slows down, and the saw blade cutting process does not generate dust. It can enter the dust collection pipe through the upper cover of the dust hood, achieving a good dust removal effect.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
