Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to an integrated device for fixing cement blankets. Background Technology

[0002] In the construction process of building engineering, in order to improve the protection of deep foundation pit slopes, cement blanket protection construction technology is often used. Cement blanket slope protection usually uses cement blanket as the slope protection material and lays it on the slope surface to prevent slope erosion, protect the soil, and beautify the environment. Cement blanket slope protection has the characteristics of being easy to use, quick to construct, high strength, good durability, environmental protection, fireproof, and waterproof.

[0003] To improve the efficiency of cement blanket laying and reduce labor intensity, a cement blanket laying device (publication number CN221645700U) has been developed. It is equipped with a winch and a roller. The roller is connected to the winch by a wire rope, and the roller clamps the end of the cement blanket through a clamping structure. Under the pull of the wire rope of the winch, the roller rolls towards the bottom of the slope, and drives the cement blanket to be laid from the top of the slope to the bottom of the slope. When the roller reaches the appropriate position, the clamping of the cement blanket is released, and the roller is rolled from the bottom of the slope to the top of the slope again by the wire rope. The roller flattens the cement blanket again.

[0004] For slopes requiring higher stability and firmness, it is generally necessary to lay and nail the cement blanket from bottom to top to ensure better adhesion to the ground. However, existing cement blanket laying devices are only suitable for laying from the top of the slope to the bottom. Furthermore, cement blanket laying requires manual nailing with a hand-held nail gun. During the nailing process, the operator needs to climb the slope, which is dangerous and can easily cause the cement blanket to wrinkle or slip. Utility Model Content

[0005] To address the technical problem in the background art that existing cement blanket laying devices cannot be used for laying and nailing cement blankets from bottom to top, resulting in limited cement blanket laying quality, this utility model provides an integrated cement blanket laying and fixing device.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides an integrated device for fixing and laying cement blankets, including a frame. Along its length, the frame is sequentially equipped with a first motor, a cement blanket support unit, and a belt assembly. The first motor is connected to the belt assembly via a sprocket and chain. The belt assembly includes two opposing belts. A clamping unit is fixedly installed on the surface of each belt near the cement blanket support unit. An automatic nailing mechanism is fixedly installed at the other end of the two belts. The automatic nailing mechanism is located in the upper section of the belt, and the clamping unit is located in the lower section of the belt. The belts can clamp and fix the end of the cement blanket through the clamping unit, and the belts drive the cement blanket to move, allowing it to be laid from the bottom of the slope towards the top. Simultaneously, the automatic nailing mechanism moves to the bottom of the slope. During the resetting process of the clamping unit, the automatic nailing mechanism nails the cement blanket from the bottom to the top of the slope, effectively preventing the cement blanket from slipping and avoiding personnel climbing, thus ensuring the quality of the cement blanket laying.

[0008] Preferably, the cement blanket support unit includes a detachably connected mounting base and a support rod. There are two mounting bases, which are fixedly mounted on the frame. The support rod is rotatably mounted between the two mounting bases, which facilitates the installation and support of the cement blanket roll.

[0009] Preferably, the automatic nailing mechanism includes two opposing movable bases, which are fixedly mounted on the upper section of the adjacent belt. A lead screw is rotatably connected between the two movable bases, and a drive motor connected to the lead screw is fixedly mounted on the movable base. The lead screw is arranged along the width direction of the frame, and a nut is threaded onto the lead screw. A nailing unit is fixedly connected to the nut. Driven by the lead screw and nut, the automatic nailing mechanism can move in the width direction of the frame, thereby increasing its working range.

[0010] Preferably, a pressure roller is rotatably mounted on the movable base, which can roll and press the cement blanket during the movement, eliminate the gap between the cement blanket and the slope, avoid wrinkles in the cement blanket, and improve the laying quality of the cement blanket.

[0011] Preferably, the pressure roller is located on the side of the screw away from the cement blanket support unit, which can roll the cement blanket before the automatic nailing mechanism nails, avoid wrinkles in the cement blanket, and effectively improve the laying quality of the cement blanket.

[0012] Preferably, the nailing unit includes a spring pusher, a nail box, and a nail-laying device connected in sequence. The spring pusher is connected to a second motor fixedly mounted on the nailing unit via a drive shaft and a belt assembly, which improves the automation level of the nailing operation.

[0013] Preferably, the bottom of the frame is equipped with rollers for easy movement of the entire device. The bottom of the frame with the first motor is hinged with a support leg for contact with the ground during operation, which supports the entire device and ensures stability during operation.

[0014] As can be seen from the above technical solutions, the advantages of this utility model are:

[0015] 1. The automatic nailing mechanism and the clamping unit are positioned opposite each other at both ends of the belt, with the automatic nailing mechanism located on the upper section of the belt and the clamping unit located on the lower section of the belt. The belt can clamp and fix the end of the cement blanket through the clamping unit, and the belt can drive the cement blanket to move, so that the cement blanket can be laid from the bottom of the slope to the top of the slope. At the same time, the automatic nailing mechanism can move to the bottom of the slope simultaneously. During the resetting process of the clamping unit, the automatic nailing mechanism performs nailing operation on the cement blanket in the direction from the bottom of the slope to the top of the slope. This not only effectively prevents the cement blanket from slipping, but also avoids personnel climbing, ensuring the laying quality of the cement blanket.

[0016] 2. A pressure roller is rotatably mounted on the movable base, and the pressure roller is located on the side of the screw away from the clamping unit. It can roll the cement blanket before the automatic nailing mechanism nails, eliminate the gap between the cement blanket and the slope, avoid wrinkles in the cement blanket, and effectively improve the laying quality of the cement blanket.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] In a typical embodiment of this utility model, such as Figures 1-2 As shown, an integrated cement blanket paving and fixing device is proposed, including: a frame, a drive unit, a cement blanket support unit, a belt assembly, an automatic nailing mechanism, and a control unit 16. The drive unit is fixedly installed on the frame and connected to the belt assembly for driving the rotation of the belt assembly. The cement blanket support unit is fixedly installed on the frame for installing cement blanket rolls. The automatic nailing mechanism is slidably installed on the frame and can move along the length of the frame to nail the cement blanket. The control unit 16 is fixedly installed on the frame and contains a human-machine interface, serving as the control center of the entire device.

[0025] Specifically, the frame includes a mounting frame 1 and a telescopic frame 2. The mounting frame 1 is fixedly connected to the telescopic frame 2. The drive unit is a first motor 3. The first motor 3 and the control unit 16 are fixedly mounted on the mounting frame 1. The telescopic frame 2 consists of two opposing long frames. The belt assembly includes pulleys 6 and belts 7. Two pulleys 6 are rotatably provided at the end of the telescopic frame 2 that is fixedly connected to the mounting frame 1. The two pulleys 6 are opposite to each other and are fixedly connected by a rotating shaft. The rotating shaft is rotatably mounted on the telescopic frame 2, and a sprocket is fixedly provided at one end of the rotating shaft. A sprocket is also fixedly provided on the output shaft of the first motor 3. The first motor 3 is connected to the sprocket at the end of the rotating shaft through a chain to drive the rotating shaft to rotate around the shaft, thereby driving the two pulleys 6 to rotate synchronously around the shaft. Two opposing pulleys 6 are also rotatably provided at the end of the telescopic frame 2 away from the mounting frame 1. The two pulleys 6 located on the same side at both ends of the telescopic frame 2 are connected by a belt 7. The two belts 7 extend along the length of the telescopic frame 2 and are opposite to each other.

[0026] A cement blanket support unit is fixedly installed on the telescopic frame 2. The cement blanket support unit includes a mounting base 4 and a support rod 5. There are two mounting bases 4. The two mounting bases 4 are fixedly installed on the telescopic frame 2 by welding, bolt connection or other means. The support rod 5 is detachably installed between the two mounting bases 4 for the installation support of the cement blanket roll. The support rod 5 is rotatably connected to the mounting base 4.

[0027] In this embodiment, the mounting base 4 is an openable and lockable annular structure. The support rod 5 is rotatably disposed within the annular structure, and baffles are fixed at both ends of the support rod 5 to restrict the axial movement of the support rod 5. This allows the support rod 5 to rotate while also being disassembled.

[0028] It is understandable that the specific structure of the mounting base 4 and the support rod 5 can be selected according to the actual design requirements, and no further restrictions will be imposed here.

[0029] A clamping unit 8 is fixedly installed on the outer surface of one end of each belt 7 near the mounting frame 1. The two clamping units 8 are arranged opposite each other. The end of the cement blanket can be clamped and fixed by the clamping unit 8. When the belt 7 is driven to rotate, the clamping unit 8 can be moved, thereby realizing the stretching and laying of the cement blanket. In this embodiment, the clamping unit 8 includes two clamping plates, which are connected by bolts. The end of the cement blanket can be clamped by the clamping plates. In other embodiments, it can also be set as a magnetic clamping plate structure as in the prior art. The specific structural form is not limited here, as long as it can achieve the clamping and fixing of the end of the cement blanket.

[0030] The automatic nailing mechanism is slidably mounted on the telescopic frame 2. In this embodiment, the automatic nailing mechanism is horizontally fixed on two belts 7. In the initial working state, the automatic nailing mechanism is located at the end of the belt 7 away from the clamping unit 8, and the automatic nailing mechanism is located above the clamping unit 8. Specifically, in the initial working state, the automatic nailing mechanism and the clamping unit 8 are located opposite each other at both ends of the belt 7, and the automatic nailing mechanism is located on the upper section of the belt 7 (i.e., the part of the belt 7 above the pulley), and the clamping unit 8 is located on the lower section of the belt 7 (i.e., the part of the belt 7 below the pulley). Thus, when the belt 7 rotates to lay the cement blanket, the automatic nailing mechanism will move in the opposite direction to the direction of the cement blanket movement. During the process of the clamping unit 8 releasing the cement blanket and resetting, the automatic nailing mechanism simultaneously resets and nails the laid cement blanket to fix it. The overall structure is relatively simple and the synchronization degree is high.

[0031] In other embodiments, the automatic nailing mechanism can also be directly coupled to the telescopic frame 2. For example, a motor-driven lead screw pair structure can be installed on the telescopic frame 2, and the automatic nailing mechanism can be installed on the lead screw pair. In this way, the lead screw pair can drive the automatic nailing mechanism to move along the length direction of the telescopic frame 2, and no longer move synchronously with the belt 7.

[0032] Understandably, the movement method of the automatic nailing mechanism can be selected according to actual design requirements, preferably mounted on belt 7, in order to simplify the structure and improve synchronization.

[0033] like Figure 3 As shown, the automatic nailing mechanism includes a movable base 9, a lead screw 10, a pressure roller 11, and a nailing unit 12. In this embodiment, the movable base 9 is fixedly mounted on the belt 7 by bolt connection. The lead screw 10 is rotatably mounted on the movable base 9. A drive motor (not shown in the figure) is also fixedly mounted on the movable base 9. The drive motor is connected to the lead screw 10 to drive the lead screw 10 to rotate around the axis. The lead screw 10 is perpendicular to the length direction of the telescopic frame 2. A nut is fixedly connected to the bottom of the nailing unit 12 and is threadedly connected to the lead screw 10 through the nut. Thus, the nailing unit 12 can be driven by the lead screw 10 to move along the width direction of the telescopic unit 2 to meet the nailing needs at different positions. The pressure roller 11 is rotatably mounted on the movable base 9 through a rotating shaft and is located on the side of the lead screw 10 away from the cement blanket support unit. It is used to roll the cement blanket before nailing to eliminate the gap between the cement blanket and the slope and improve the laying quality. The pressure roller 11 is located between the two long strips of the telescopic frame 2.

[0034] like Figure 3 As shown, there are two movable bases 9 arranged opposite each other. The movable bases 9 are inverted L-shaped structures. The top horizontal plate of the movable base 9 is clamped and fixedly connected to the upper section of the corresponding belt 7 by bolts and nuts. An installation plate is welded and fixed to the inner side wall of the movable base 9 below the upper section of the belt 7. A rotating shaft is provided between the two opposite movable bases 9. The end of the rotating shaft is fixedly mounted on the installation plate (in actual installation, a rotating shaft support can be set on the installation plate), and the pressure roller 11 is rotatably mounted on the rotating shaft.

[0035] A second motor 13 is fixedly installed on the nailing unit 12. A nail box, a nail-laying device, and a spring pusher are fixedly installed inside the nailing unit 12. The second motor 13 is connected to the drive shaft through a belt assembly. The drive shaft is connected to the nail box through the spring pusher. The spring pusher converts the input rotational motion into linear motion to push the nails in the nail box into the nail-laying device, and then uses the nail-laying device to perform the nailing operation.

[0036] In this embodiment, the nail-laying device is an existing automatic nail-laying structure. In other embodiments, the nail-laying device can also be a conventional nail gun structure. In this case, a nail-driving motor and a counterweight structure are also required. The counterweight is connected to the nail-driving motor using a crank-connecting rod structure. The nail-driving motor drives the counterweight to make pitching motion through the crank-connecting rod structure. The nail-driving action is controlled by the collision between the counterweight and the driving unit of the nail gun.

[0037] like Figure 1 As shown, the bottom of the frame is also equipped with rotatable rollers 14 to facilitate the overall transfer of the device. The bottom of the mounting frame 1 is also hinged with support legs 15 to contact the ground during operation, thereby supporting the overall device and ensuring stability during operation.

[0038] The specific working principle is as follows:

[0039] The cement blanket roll is installed on the support rod 5, and the end of the cement blanket is clamped and fixed using the clamping unit 8. The entire device is placed at an angle on the slope so that the mounting frame 1 is located at the bottom of the slope and is supported and limited by the support leg 15.

[0040] The first motor 3 is started, and the belt 7 rotates, driving the clamping unit 8 and the automatic nailing mechanism to move synchronously. Specifically, the clamping unit 8 moves the cement blanket from below the belt 7 along the slope towards the top of the slope, while the automatic nailing mechanism moves from above the belt 7 along the slope towards the bottom of the slope. After the cement blanket is in place, the clamping unit 8 is released manually or electromagnetically controlled, and the first motor 3 drives the belt 7 to rotate in the opposite direction, causing the clamping unit 8 to move towards the bottom of the slope, while the automatic nailing mechanism moves towards the top of the slope. During the movement of the automatic nailing mechanism, the pressure roller 11 is used to flatten the cement blanket to avoid wrinkles. During the movement of the automatic nailing mechanism, the nailing unit 12 performs the nailing work, eliminating the need for personnel to climb the slope to nail.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
