Description

Technical Field

[0001] The utility model relates to the technical field of laying devices, in particular to a flexible concrete blanket laying device. Background Technique

[0002] A flexible concrete blanket is a new type of building material. The flexible concrete blanket only needs to be watered to undergo a hydration reaction and quickly harden into the required shape and hardness. The flexible concrete blanket can be widely used in fields such as water conservancy, transportation, and agriculture, such as slope protection, canal flood discharge, and landscape lake slope protection.

[0003] Among them, in slope protection projects, it is necessary to transport the concrete blanket to the top of the slope, and then manually push the rolled concrete blanket. The concrete blanket rolls down the slope to the bottom of the slope. After manual fine-tuning of the laying position of the concrete blanket, the laying work of the concrete blanket is completed. During actual construction, the concrete blanket quickly falls and unfolds along the slope. Since the unfolding speed of the concrete blanket is uncontrollable, the laying position of the concrete blanket is prone to deviation, which is not conducive to fine-tuning the laying position of the concrete blanket in the later stage. Therefore, we propose a flexible concrete blanket laying device. Content of the Utility Model

Detailed implementation manners

[0025] In this embodiment, as shown in Figure 1 and Figure 2 A flexible concrete blanket laying device includes a concrete blanket body 1, and a laying assembly 2 is arranged on the concrete blanket body 1. The laying assembly 2 is used to control the unfolding speed of the concrete blanket body 1. The laying assembly 2 includes a rewinding shaft 21, a snap ring 22, a towing rope 23, a sheave 24, a support shaft 25, a bearing bracket 26 and a driving member 27. The outer periphery of the rewinding shaft 21 is fixedly connected to the unfolding end of the concrete blanket body 1. The snap ring 22 is sleeved at both ends of the rewinding shaft 21. The towing rope 23 is fixedly connected to the outer periphery of the snap ring 22. One end of the sheave 24 away from the snap ring 22 is fixedly connected to the towing rope 23. Both ends of the support shaft 25 are fixedly connected to the sheave 24. The bearing bracket 26 is connected to the support shaft 25 through a bearing. The driving member 27 is used to drive the support shaft 25 to rotate.

[0026] Thus, after the concrete blanket body 1 is wound around the outer wall of the rewinding shaft 21, the snap ring 22 is inserted into both ends of the rewinding shaft 21. The concrete blanket body 1 is placed on the slope through the bearing bracket 26, and the slope is laid by using the unfolding of the concrete blanket body 1. Under the action of the driving member 27, the support shaft 25 rotates in the bearing bracket 26. At the same time, the towing rope 23 in the sheave 24 gradually separates from the sheave 24. At this time, the concrete blanket body 1 unfolds downward along the slope. By controlling the rotation speed of the support shaft 25 in the bearing bracket 26, the unfolding speed of the concrete blanket body 1 is further controlled.

[0027] Further, one end of the concrete blanket body 1 is fixedly connected to the winding shaft 21. The winding shaft 21 winds up the concrete blanket body 1. There are two snap rings 22. The traction rope 23 connects the snap rings 22 and the grooved pulley 24. The grooved pulley 24 is used to wind up the traction rope 23. The two grooved pulleys 24 are symmetrically distributed at both ends of the support shaft 25.

[0028] In some embodiments, as Figure 3 shown, the driving member 27 includes a motor frame 271, a transmission shaft 272, a first gear 273, a second gear 274 and a motor 275. The bottom end of the motor frame 271 is fixedly connected to the bearing bracket 26. The transmission shaft 272 is rotatably connected to the motor frame 271 through a bearing. The central hole of the first gear 273 is fixedly connected to the transmission shaft 272. The second gear 274 is fixedly connected to the outer periphery of the transmission shaft 272. The second gear 274 is meshed and connected to the first gear 273. The output end of the motor 275 is fixedly connected to the transmission shaft 272.

[0029] Further, the motor frame 271 supports the transmission shaft 272. The side wall of the first gear 273 is evenly distributed with card slots adapted to the positioning pins 271a. The first gear 273 drives the second gear 274 to rotate, and then drives the support shaft 25 to rotate. The motor 275 is a servo motor.

[0030] In some embodiments, as Figure 1 and Figure 4 shown, a clamping assembly 3 is installed on the bearing bracket 26. The clamping assembly 3 is used to fix one end of the concrete blanket body 1 away from the winding shaft 21. The clamping assembly 3 includes a right-angle plate 31, a U-shaped frame 32, a screw 33, a pressing plate 34 and a turning knob 35. The bottom end of the right-angle plate 31 is fixedly connected to the bearing bracket 26. The U-shaped frame 32 is fixedly connected to the top end of the right-angle plate 31. The screw 33 is in threaded connection with the U-shaped frame 32. The pressing plate 34 is fixedly connected to the bottom end of the screw 33. The bottom end of the pressing plate 34 abuts against the concrete blanket body 1. The turning knob 35 is fixedly connected to the top end of the screw 33.

[0031] Further, the design of the right-angle plate 31 semi-wraps the top of the bearing bracket 26. The through groove formed by the U-shaped frame 32 and the top surface of the right-angle plate 31 is used to fix the concrete blanket body 1. There are four screws 33 to increase the stability when fixing the concrete blanket body 1. The lower surface of the pressing plate 34 is processed with abrasive patterns to increase the friction with the concrete blanket body 1. The screw 33 is driven to rotate by the turning knob 35.

[0032] In some embodiments, as Figure 4 shown, rollers 262 are installed at the bottom of the bearing bracket 26. The rollers 262 are used to adjust the use position of the bearing bracket 26.

[0033] Further, four rollers 262 are provided. The design of the four rollers 262 facilitates the transportation of the concrete blanket body 1 to the slope.

[0034] In some embodiments, as Figure 5 shown, a guide rod 261 is rotatably connected in the bearing bracket 26. The guide rod 261 is used to support the towing rope 23.

[0035] Further, the arrangement of the guide rod 261 is used to carry the towing rope 23, reducing the friction between the towing rope 23 and the bearing bracket 26 during retraction and extension.

[0036] In some embodiments, as Figure 3 shown, a positioning pin 271a is threadedly connected in the motor bracket 271. The positioning pin 271a is used to fix the position of the first gear 273 in the motor bracket 271.

[0037] Further, when the positioning pin 271a is inserted into the groove of the first gear 273, it can limit the rotation of the transmission shaft 272 in the motor bracket 271.

[0038] The working principle of the present application will be described below with a preferred embodiment:

[0039] After one end of the concrete blanket body 1 is fixedly connected to the winding shaft 21, the winding shaft 21 is then used to wind the concrete blanket body 1. Subsequently, the snap ring 22 is inserted into both ends of the winding shaft 21, and the other end of the concrete blanket body 1 is placed in the U-shaped frame 32. By rotating the knob 35 to rotate the screw 33, the screw 33 drives the pressing plate 34 to move downward. Further, multiple pressing plates 34 cooperate with the right-angle plate 31 to fix the concrete blanket body 1. After the overall mechanism is driven by the rollers 262 at the bottom of the bearing bracket 26 to move to a suitable position, the positioning pin 271a is rotated to separate from the first gear 273, and the motor 275 is started to drive the transmission shaft 272 to rotate in the motor bracket 271. The transmission shaft 272 drives the second gear 274 to rotate through the first gear 273. Further, the support shaft 25 rotates in the bearing bracket 26 along with the second gear 274. At this time, the towing rope 23 on the grooved pulley 24 gradually separates from the grooved pulley 24, and the towing rope 23 unfolds downward along the slope with the concrete blanket body 1 through the snap ring 22, thereby controlling the unfolding speed of the concrete blanket body 1 along the slope.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
