[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-Figure 10The construction elevator with high stability shown in the figure comprises a lifting frame 1 and a lifting mechanism 2 installed on the upper inner side of the lifting frame 1. A slide 3 is arranged on the outer side of one end of the lifting mechanism 2.

A roller bin 25 is fixedly installed on the upper end surface of the base 7. A plurality of rollers 8 are rotatably connected to the inner side of the roller bin 25. A plurality of rollers 8 are arranged inside the roller bin 25, so that the cement bags finally stacked on the upper surface can be pushed conveniently. Tracks 1 are arranged on both sides of the base 7. 0, one end of the outer side of the two sets of tracks 10 is connected to a slide plate 24 through a set driving mechanism, one side of the two slide plates 24 is fixedly connected to a sliding sleeve, the upper end surfaces of the two sets of sliding sleeves are fixedly provided with a second hydraulic cylinder 26, the upper end surfaces of the two sets of second hydraulic cylinders 26 are fixedly installed with a connecting seat 5, the upper end surfaces of the two connecting seats 5 are jointly provided with a bag pushing mechanism, and the outer sides of the two sets of second hydraulic cylinders 26 are provided with a protective component. Under the telescopic drive of the second hydraulic cylinder 26, the connecting seat 5 will drive the bag pushing mechanism to press and push, so that cement bags with different stacking heights can be loaded; The lifting mechanism 2 is a commonly used driving structure for lifts, and is composed of components such as a driving motor, a reinforcing screw, and a threaded sleeve, which are prior arts and will not be described in detail.

[0018] The driving mechanism includes a support seat 27 fixedly mounted on one end of the outer side of the track 10, and a first hydraulic cylinder 9 is fixedly mounted on the upper end surface of the support seat 27. The telescopic end of the first hydraulic cylinder 9 is fixedly connected to the outer side of the slide plate 24. The first hydraulic cylinder 9 is connected to the support seat 27 and is stably driven on one side of the track 10, so that the slide plate 24 can move outside the track 10, thereby achieving the purpose of pushing the cement bag.

[0019] The bag pushing mechanism includes a mounting rod 4 jointly mounted on the upper end surfaces of the two connecting seats 5, both ends of one side of the mounting rod 4 are fixedly connected to mounting blocks 34, and a screw rod 33 is rotatably mounted on the inner sides of the two groups of mounting blocks 34, one end of the screw rod 33 passes through the outer side of the corresponding mounting block 34 and a motor 31 is fixedly mounted on the end thereof, the motor 31 is mounted on the outer side of the corresponding mounting block 34, a slider 32 is threadedly sleeved on the outer side of the screw rod 33, one side surface of the slider 32 is slidably fitted with the outer wall of the mounting rod 4, one side of the slider 32 is fixedly connected to an arc seat 28, a rubber pad 30 is fixedly mounted on the inner surface of the arc seat 28, a bag rowing assembly is arranged on the rear end surface of the arc seat 28, and rolling assemblies are arranged on both ends of the bottom of the arc seat 28. After the motor 31 is connected to an external power supply, it can drive the screw rod 33 to rotate, and cooperate with the screw rod 33 threadably and under the sliding limit of the mounting rod 4, the slider 32 can drive the arc seat 28 to translate laterally on the outside of the mounting rod 4. This measure can facilitate bag rowing in the later stage.

[0020] The bag rowing assembly includes a clamping plate 38 symmetrically installed on the rear end surface of the arc seat 28, and a mounting seat 39 is movably inserted into the inner sides of the two clamping plates 38. A blade 35 is fixedly installed on the outer side of the mounting seat 39. The blade 35 is movably inserted into the two clamping plates 38 through the arranged mounting seat 39. Both ends of the clamping plate 38 located at the top are fixedly connected with positioning blocks 40, and positioning pins 41 are threadedly inserted into the inner sides of the two positioning blocks 40, and one end of the positioning pin 41 extends to the inside of the mounting seat 39 accordingly. The positioning block 40 cooperates with the positioning pin 41 to insert from the corresponding clamping plate 38 into the inside of the mounting seat 39, so as to fix the mounting seat 39, making it more convenient for the blade 35 to row the bag. At the same time, the blade 35 can also be taken out from one end of the two clamping plates 38 through the above structure, and then flexibly replaced according to the wear condition.

[0021] The rolling assembly includes a bottom box 29 fixedly mounted on the bottom of the arc seat 28, with rubber sleeves 36 fixedly mounted on both ends of the inner side of the bottom box 29, and an insert roller 37 installed inside the two rubber sleeves 36, and a roller sleeve is rotatably mounted in the middle of the outer side of the insert roller 37. The rubber sleeves 36 are arranged on both sides of the bottom box 29 to facilitate the installation of the insert roller 37. When pushing the cement bags in the later stage, the bottom can roll in contact with the surface of the stacked cement bags at the lower end, thereby avoiding hard contact between the bottom box 29 and the cement bags.

[0022] The protection component includes a holder 42 sleeved on the outside of the second hydraulic cylinder 26. The installation of the holder 42 allows the fixed box 22 to be set outside the second hydraulic cylinder 26 for use, so that components such as the fence 6 can be used flexibly. The fixed box 22 is fixedly installed on one side of the holder 42, and a buckle rod 23 is movably arranged inside the fixed box 22. The fence 6 is fixedly installed on the upper end surface of the buckle rod 23. Multiple limit rods 43 are slidably inserted inside both sides of the fixed box 22, and the ends of the multiple limit rods 43 are jointly installed with a pull rod 18. A clamping ring 19 is fixedly sleeved on the outside of the multiple limit rods 43 and located on one side of the fixed box 22. A spring 20 is mounted on the outside of the plurality of limit rods 43 and at one end of the retaining ring 19. A positioning frame 21 is slidably mounted on the outside of the plurality of limit rods 43. The plurality of positioning frames 21 are fixedly connected to the fixing box 22. The end of the spring 20 away from the retaining ring 19 is against the inner surface of the positioning frame 21, and one end of the plurality of limit rods 43 is movably inserted into the buckle rod 23. The plurality of limit rods 43 are pulled by the pull rod 18 to squeeze the external spring 20, causing the front end of the limit rod 43 to detach from the inside of the buckle rod 23. Therefore, the fence 6 can be flexibly installed according to the needs of use, and can meet the transportation of other building materials.

[0023] A first connecting rod 14 and a second connecting rod 16 are respectively installed at one end of the two groups of fences 6. The upper and lower ends of the outer side of the first connecting rod 14 are rotatably mounted with a notch seat 15. The two groups of notch seats 15 are made of rubber material. Semicircular bayonet slots are opened at equal distances along the circumferential direction on the inner side of the notch seat 15, and the notch seat 15 can be made of a relatively hard rubber material. In conjunction with the clamping of the clamping rod 13, it needs to be pressed hard to ensure blocking use under normal circumstances.

[0024] The upper and lower ends of the outer side of the second connecting rod 16 are rotatably mounted with rotating wheels 17, and a baffle 11 is commonly installed on the outer sides of the two sets of rotating wheels 17. A clamping rod 13 is fixedly mounted on the edge of one end of the baffle 11 away from the rotating wheel 17, and the clamping rod 13 is movably mounted with the notch seat 15. The baffle 11 can be rotatable on the outside of the second connecting rod 16 through the rotating wheel 17 arranged on one side, so that it is more convenient to put on cement bags. The movable clamping of the clamping rod 13 and the notch seat 15 can also be convenient for workers to use and prevent workers from carelessly stepping on the front end of the roller bin 25. Since the notch seat 15 is made of rubber material, when the clamping rod 13 is inserted into the internal notch, it can meet the basic protection capability under normal conditions. When transporting cement bags, the arc seat 28 is used to press on the top of the cement bags, and the cement bags are relatively stable during transportation.

[0025] Working principle: The cement bag can be placed above the roller bin 25, and then driven by the lifting mechanism 2, causing the slide 3 to drive the base 7 and the roller bin 25 to rise. During the rising process, the fences 6 on both sides and the baffle 11 at the front end can protect the cement bags above the roller bin 25, so that the cement bags can be stably transported above the roller bin 25, which greatly improves the safety of high-altitude transportation of building materials. When unloading, the height of the arc seat 28 is kept parallel to the cement bag currently pushed by the second hydraulic cylinder 26, and then Driven by the first hydraulic cylinder 9, the cement bag slides out from the top of the roller bin 25 through the push of the arc seat 28. According to the needs of the workers, the cement bag can be cut open by the blade 35 at the rear end of the arc seat 28, so as to facilitate the workers to take it. When transporting multiple groups of cement bags, just repeat the above steps in sequence. In this way, the elevator can provide great convenience to people when transporting cement bags. At the same time, the seat 42 and the fixed box 22 on the outside of the second hydraulic cylinder 26 and the baffle 11 at the front end are all in the lifting process, which enhances the safety performance.
