Description

Technical Field

[0001] The invention relates to the technical field of roadbed construction, and in particular to a subway track roadbed casting device. Background Art

[0002] Ballast bed pouring is an important process in rail transit construction, which mainly involves pouring concrete under the track to form a stable track foundation. Figure 1 , it is necessary to first set up the steel skeleton 600, then set the template 500 around the steel skeleton 600, and then inject concrete into the template 500. After injecting the concrete, it needs to be vibrated, and during the vibration, it is necessary to manually hold a tamping rod, but because the steel skeleton 600 is relatively dense, the tamping rod needs to be lifted up and then moved to another gap in the steel skeleton 600, which is very inconvenient during the construction process.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0024] like Figure 1-Figure 5 As shown, the present embodiment discloses a subway track ballast casting device, which is particularly suitable for use in the subway track ballast casting in a tunnel. The subway track ballast casting device of the present embodiment includes two temporary tracks 200, and the two temporary tracks 200 are temporarily fixed on both sides of the tunnel 100 through mounting frames, respectively. A first traveling vehicle 300 is provided on each temporary track 200, and the first traveling vehicle 300 can travel along the temporary track 200. This is a prior art and will not be described in detail herein.

[0025] The upper sides of the two first trolleys 300 are fixedly connected to a transverse track 400 , on which a second trolley is arranged. The second trolley is also prior art and can travel along the transverse track 400 . The second trolley is not shown in the attached drawings.

[0026] The lower side of the second traveling vehicle is connected to a concrete storage box 1 through a suspension rod, and a feeding device 2 is provided on both sides of the concrete storage box 1; the feeding device 2 includes a vertical pipe 21, one side of the vertical pipe 21 is connected to the concrete storage box 1 through a connecting pipe 22, and the connecting pipe 22 also serves as a bridge connecting the vertical pipe 21 and the concrete storage box 1. A cover plate 20 is fixedly connected to the upper end of the vertical pipe 21, and a first motor 24 is installed on the cover plate 20. An auger is fixedly connected to the main shaft of the first motor 24, and the auger is arranged in the vertical pipe 21. A telescopic tube 23 is slidably connected to the interior of the lower end of the vertical pipe 21, an electric telescopic rod 25 is installed on the cover plate 20, the telescopic end of the electric telescopic rod 25 is fixedly connected to a connecting plate 26, the connecting plate 26 is fixed to the telescopic tube 23, the lower end of the telescopic tube 23 is connected to a feeding pipe 3 with a telescopic curved pipe structure, a disturbance device 5 is installed on the feeding pipe 3, the disturbance device 5 can drive the feeding pipe 3 to vibrate and cause disturbance to the concrete; when the feeding pipe 3 is fully retracted, its lower end is in a tilted downward state.

[0027] The feeding pipe 3 includes a base pipe, which includes a vertical section 31 and a curved section 32. The upper end of the vertical section 31 is fixedly connected to the lower end of the telescopic tube 23, and the lower end of the vertical section 31 is fixedly connected to the upper end of the curved section 32. The outer side of the curved section 32 is slidably connected with a sleeve 33. The curved section 32 and the sleeve 33 are arc tubes with the same center. The sleeve 33 is equipped with an arc rack 34 with the same center as the sleeve 33. The vertical section 31 is fixedly equipped with a second motor 57. The main shaft of the second motor 57 is equipped with a gear 35 that meshes with the arc rack 34. The gear 35 is driven to rotate by the second motor 57. Since the gear 35 meshes with the arc rack 34, the sleeve 33 can be driven to slide along the curved section 32.

[0028] The disturbance device 5 includes a bracket, which is fixed on the upper side of the lower end of the sleeve 33. The bracket is composed of two vertical plates 51, and a slide groove is vertically arranged on the vertical plate 51. A cross bar 52 is arranged between the two vertical plates 51. The two ends of the cross bar 52 are respectively slidably arranged in the two slide grooves. A first spring 53 is connected between the lower side of the two slide grooves and the cross bar 52. The cross bar 52 can vibrate up and down. A vibration rod 54 is arranged on the lower side of the cross bar 52. A contact block 55 that can contact the sleeve 33 is arranged on the lower side of the vibration rod 54. The surface of the contact block 55 is an arc surface. The vibration rod 54 contacts the sleeve 33 through the contact block 55. During the working process, the vibration of the vibration rod 54 can drive the sleeve 33 to vibrate, so as to prevent the concrete from being blocked in the sleeve 33.

[0029] A crankshaft 56 located above and parallel to the crossbar 52 is also rotatably connected between the two vertical plates 51, and a ball 58 is provided at the middle eccentric portion of the crankshaft 56. A third motor 59 for driving the crankshaft 56 is installed on one of the vertical plates 51. When the third motor 59 drives the crankshaft 56 to rotate, the ball 58 rotates eccentrically in the concrete along with the crankshaft 56, thereby disturbing the concrete and acting as a vibrator. In addition, when the ball 58 rotates eccentrically along with the crankshaft 56, the ball 58 can also squeeze the crossbar 52, so that the vibration rod 54 can be in closer contact with the sleeve 33, and the vibration force generated on the sleeve 33 will suddenly increase intermittently, which can further prevent the concrete from being blocked in the sleeve 33. At the same time, it can also prevent the vibration rod 54 from generating a large vibration force on the sleeve 33 for a long time, causing the sleeve 33 to deform.

[0030] like Figure 4 As shown, a beating device 4 is installed between the two base pipes and located above the disturbance device. The beating device 4 is used to beat the concrete.

[0031] The beating device 4 includes a mounting beam 6 and a beating plate 43. The mounting beam 6 is fixedly connected between the vertical sections 31 of the two base pipes. The mounting beam 6 is provided with a plurality of sliding holes. The sliding holes are provided with a sliding rod 41 that can slide back and forth up and down. A top plate 42 is provided at the top of the sliding rod 41. A second spring 45 sleeved on the sliding rod 41 is connected between the top plate 42 and the mounting beam 6. The beating plate 43 is fixedly connected to the lower end of each sliding rod 41. A counterweight 44 is provided on the beating plate 43. At the same time, when the ball 58 rotates eccentrically following the crankshaft 56, the ball 58 will squeeze the beating plate 43 upward. When the ball 58 leaves, the beating plate 43 beats the concrete under the elastic force of the second spring 45. On the one hand, the concrete accumulated in the middle can be evenly beaten, and on the other hand, the concrete surface can be flattened to improve the pouring quality.

[0032] In other embodiments, the beating device 4 may also be installed between two telescopic tubes, that is, the mounting beam is fixedly connected between the lower ends of the two telescopic tubes.

[0033] During use of the subway track bed casting device of this embodiment, the electric telescopic rod 25 drives the telescopic tube 23 to contract, and the telescopic tube 23 can lift the feeding device 2, the disturbance device 5 and the slapping device 4. At the same time, the feeding tube 3 of the feeding device 2 contracts. Then, the first traveling vehicle 300 can drive the concrete storage box 1, the feeding device 2, the disturbance device 5 and the slapping device 4 to move on the temporary track 200 in the tunnel 100. The feeding device 2, the disturbance device 5 and the slapping device 4 will not collide with the steel skeleton 600. Similarly, the second traveling vehicle can also drive the concrete storage box 1, the feeding device 2, the disturbance device 5 and the slapping device 4 to translate on the transverse track 400, thereby realizing casting at different positions. During pouring, the telescopic tube 23 is extended by the electric telescopic rod 25, and the telescopic tube 23 can lower the feeding device 2, the disturbance device 5 and the slapping device 4, so that the feeding tube 3 of the feeding device 2 is inserted into the gap of the steel skeleton 600 for pouring. The sleeve 33 can be driven to slide along the curved section 32 of the base pipe by the second motor 57, the gear 35 and the arc-shaped rack 34, and the length of the feeding tube 3 can be changed, so that different positions can be further poured to expand the pouring range. In addition, the disturbance device 5 will also enter the gap of the steel skeleton 600, and the third motor 59 of the disturbance device 5 can drive the crankshaft 56 to rotate, and the crankshaft 56 drives the ball 58 to rotate eccentrically in the concrete, thereby disturbing the concrete and playing a vibrating role, without the need for manual hand-held tamping rods to vibrate. At the same time, the vibration of the vibration rod 54 of the disturbance device 5 can drive the feeding pipe 3 to vibrate, thereby preventing the concrete from being blocked in the feeding pipe 3. It can also drive the vertical pipe 21, the telescopic pipe 23 and the base pipe to vibrate, thereby preventing the concrete from being blocked in the vertical pipe 21, the telescopic pipe 23 and the base pipe. The entire working process does not require the operator to feed and vibrate the concrete, which greatly reduces the labor intensity of the operator, reduces the labor cost, facilitates the construction and ensures safe operation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
