Description

Technical Field

[0001] The present invention relates to the field of construction engineering, and more particularly to a dust-proof and water-stop belt for a telescopic device. Background Art

[0002] A common disease in the operation of modular expansion joints is that debris on the road enters the rubber water-stop belt between the steel longitudinal beams of the expansion joint through wheels or wind, forming blockages, which affects the free expansion and contraction of the expansion device. At the same time, if there are too many debris blockages, the rubber water-stop belt between the expansion joints will be damaged and lose its function, resulting in the leakage of bridge deck sewage to the beam body, affecting the durability and service life of the bridge. The technological update of modular expansion joints, especially the improvement of waterproof and dust-proof capabilities, is very urgent. Summary of the Invention

[0085] Embodiment

[0086] The present invention will be further described below in conjunction with the accompanying drawings.

[0087] As Figure 1 、 Figure 2 shown, a dust-proof and water-stop belt for a telescopic device provided in this embodiment is composed of an upper elastic unit 11 and a lower elastic unit 12.

[0090] The working principle and beneficial effects of the above technical solution are as follows:

[0091] A dust-proof and water-stop belt for a telescopic device provided by the present invention is composed of an upper elastic unit 11 and a lower elastic unit 12 to form an inverted convex structure. The steel springs 13 are cast in the dust-proof and water-stop belt. The upper elastic unit 11 is located between the webs of adjacent longitudinal beam steels, and a small section of the upper elastic unit 11 protrudes from the top of the longitudinal beam steel. The buckles at both ends of the steel springs 13 are connected to the anchor nails welded on the webs of adjacent longitudinal beam steels. A strong adhesive can be coated between the upper elastic unit 11 and the webs of the longitudinal beam steels. A dust-proof and water-stop belt for a telescopic device proposed by the present invention is installed between the steel longitudinal beams of the expansion joint instead of a rubber water-stop belt, has the characteristics of large elastic stiffness, has the functions of waterproofing and dust-proofing, can prevent debris accumulation and blockage, can reduce the vehicle impact effect due to its large elastic stiffness, and can evenly distribute the vehicle impact load on the longitudinal beam of the telescopic device.

[0092] As an embodiment provided by the present invention, both the upper elastic unit 11 and the lower elastic unit 12 are made of porous elastic materials.

[0093] The beneficial effects of the above technical solution are as follows:

[0094] The porous elastic material has a large elastic stiffness. The upper elastic unit 11 has high elasticity and high wear resistance, and the lower elastic unit 12 has high elasticity.

[0095] In an embodiment provided by the present invention, the adjacent steel springs 13 are arranged at an interval of 200 mm.

[0096] In an embodiment provided by the present invention, the end of the upper elastic unit 11 away from the lower elastic unit 12 is 2 mm higher than the total amount of steel of the telescopic device.

[0097] In an embodiment provided by the present invention, anchor nails are welded on the web of the longitudinal beam steel every 200 mm.

[0098] As Figure 3 As shown, another installation process of the dust-proof and water-stop belt of the telescopic device provided by the present invention, for the dust-proof and water-stop belt of the telescopic device, includes the following steps:

[0099] Step 1: Weld the side beam on one side of the telescopic device. One end of the steel spring located inside the dust-proof and water-stop belt of the telescopic device is connected to the anchor nail welded on the side beam through a buckle;

[0100] Step 2: Temporarily fix the longitudinal beam of the telescopic device. The other end of the steel spring inside the dust-proof and water-stop belt of the telescopic device is connected to the anchor nail welded on the web of the longitudinal beam steel through a buckle;

[0101] Step 3: Push the longitudinal beam to the preset position, squeeze the dust-proof and water-stop belt of the telescopic device located between the longitudinal beam and the side beam to make it in a compressed state, and fix the longitudinal beam;

[0102] Step 4: Repeat Step 2 and Step 3 until the welding of the other side beam of the telescopic device is completed.

[0103] As Figure 4 As shown, in an embodiment provided by the present invention, in Step 2, the longitudinal beam is fixed by the auxiliary fixing device 14, and the auxiliary fixing device 14 includes:

[0104] A moving seat body 15;

[0105] Rollers 16, the rollers 16 are installed at the bottom end of the moving seat body 15;

[0108] An electromagnetic chuck 19, the electromagnetic chuck 19 is connected to the free end of the suspension machine 18, and the electromagnetic chuck 19 is used to hold the longitudinal beam steel;

[0109] The ejecting mechanism 10 is installed in the moving seat body 15 and is used to push the longitudinal beam section steel to a preset position;

The ejecting mechanism 10 is located between the two ejecting rods 22, and the ejecting rod 22 is used to assist in ejecting the longitudinal beam section steel.

[0111] The working principle and beneficial effects of the above technical solution are as follows:

[0112] The electromagnetic chuck 19 works to complete the adsorption of the longitudinal beam section steel. The suspension machine 18 works to drive the longitudinal beam section steel connected to the electromagnetic chuck 19 to leave the ground. The roller 16 rotates, thereby driving the moving seat body 15 to rotate, so as to move the longitudinal beam section steel to a temporary position. The suspension machine 18 stops working, and the longitudinal beam section steel is placed at the temporary position. Manually connect the buckles at both ends of the steel spring 13 to the anchor nails welded on the web of the adjacent longitudinal beam section steel. The ejecting mechanism 10 works to drive the long strip-shaped longitudinal beam section steel to be horizontally located at the preset position, thereby squeezing the telescopic device dust-proof and water-stop belt located between the longitudinal beam and the side beam. The ejecting rod 22 of the auxiliary ejecting mechanism 21 works to further limit and restrain the longitudinal beam section steel, and squeeze the strong glue, so that the dust-proof and water-stop belt is further attached to the web of the longitudinal beam section steel.

[0121] The double-headed motor 32 operates, driving the transverse translation screw 33 installed at the output end of the double-headed motor 32 to rotate. The transverse translation screw 33 drives the two transverse translation blocks 34 sleeved thereon to move synchronously in the pushing groove 31 in a direction away from or towards each other. When the two transverse translation blocks 34 move towards each other, the transverse translation blocks 34 push out the push plate 35 through the push rod 36.

[0152] The working principle and beneficial effects of the above technical solution are:

[0153] The driving motor installed at the top of the movable seat body 15 operates, driving the transmission rotating shaft installed at the output end of the driving motor to rotate, thereby driving the eccentric wheel 37 located in the power chamber 23 and installed on the transmission rotating shaft to rotate.

The extrusion wheel 40 rolls back and forth on the web of the longitudinal beam section steel while avoiding the anchor nails, thereby extruding the strong glue, making the dust-proof and water-stop belt fit more closely with the web of the longitudinal beam section steel. At this time, the longitudinal beam section steel can be welded. After the longitudinal beam section steel is welded, the transverse movement block 47 abuts against one of the abutting plates, driving the return rod 44 connected to the abutting plate to move in the direction of contraction of the third spring. The L-shaped discharge pipe 45 is communicated with the discharge port. The gas in the transmission cylinder 38 is discharged through the L-shaped discharge pipe 45 and the discharge port. The second spring 41 resets, and the wedge-shaped locking block 30 returns to the transmission cylinder 38, thereby releasing the limit on the wedge-shaped abutting block 43. At this time, the eccentric wheel 37 rotates another 90°, further releasing the force on the transmission rod 28, and the transmission rod 28 returns to its original position, and the ejecting rod 22 returns to the power chamber 23.

[0154] As Figure 6 , Figure 10 shown, in an embodiment provided by the present invention, the auxiliary ejecting mechanism 21 further includes:

[0155] A limit chamber 51, the limit chamber 51 is located in the movable seat body 15 and below the power chamber 23. The limit chamber 51 communicates with the bottom end of the movable seat body 15, and the transmission rotating shaft extends into the limit chamber 51;

[0156] A turntable 52, the turntable 52 is located in the limit chamber 51, and the turntable 52 is installed on the transmission rotating shaft;

[0157] A reciprocating groove 53, the reciprocating groove 53 is arranged in a four-leaf clover shape with its head and tail connected on the turntable 52;

[0158] A limit disk 54, the limit disk 54 is installed on the inner wall of the limit chamber 51, and the limit disk 54 is located below the turntable 52;

[0159] Limit slots 55, four of the limit slots 55 are arranged in a cross shape on the end of the limit disk 54 close to the turntable 52, and the bottom end of the limit slot 55 penetrates through the end of the limit disk 54 away from the turntable 52;

[0160] A turning rod 56, the turning rod 56 is turnably connected in the limit slot 55;

[0161] A strip hole is opened on the turning rod 56;

[0162] A limit block, the limit block is slidably connected in the strip hole, and the limit block is installed on the inner wall of the limit slot 55;

[0163] A slider 57, the slider 57 is slidably connected in the reciprocating slot 53, and the turning rod 56 is hinged to the slider 57;

[0164] A friction plate 58, the friction plate 58 is installed at the end of the turning rod 56 away from the slider 57;

[0165] A fourth spring 59, the fourth spring 59 is sleeved on the turning rod 56, and the fourth spring 59 abuts between the friction plate 58 and the end of the limit disk 54 away from the turntable 52.

[0166] The working principle and beneficial effects of the above technical solution are as follows:

[0167] The driving motor installed at the top of the moving seat body 15 works, thereby driving the transmission rotating shaft installed at the output end of the driving motor to rotate. When the eccentric wheel 37 located in the power chamber 23 and installed on the transmission rotating shaft rotates, it synchronously drives the turntable 52 that is coaxially installed with the eccentric wheel 37 on the transmission rotating shaft and is located in the limit chamber 51 to rotate. With the cooperation of the reciprocating slot 53 on the turntable 52 and the slider 57, the turning rod 56 slides downward in the limit slot 55 along the direction of the strip hole and the limit block, and the fourth spring 59 is stretched. The turning rod 56 drives the friction plate 58 to abut against the ground, thereby increasing the contact area between the moving seat body 15 and the ground and increasing the friction force of the moving seat body 15. At this time, when the pushing plate 35, the pushing rod 22 and the pressing wheel 40 abut against the web of the longitudinal beam section steel, due to the increase in the friction force of the moving seat body 15, the reverse force is reduced and offset, enhancing the stability of the moving seat body 15.

[0168] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
