For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] In this embodiment, a small prefabricated component installation auxiliary trolley is disclosed. Figure 1 to Figure 2 The small prefabricated component installation auxiliary trolley in this embodiment includes a support frame 1, a balance bar 2, a clamping assembly 3, a handle 4 and a first fastener. Among them, the support frame 1 adopts a triangular truss structure, which has the advantages of being firm and stable. An axle 11 is fixedly arranged at the bottom of the support frame 1, and wheels 12 are rotatably arranged at both ends of the axle 11; a first adjustment cylinder 71 is arranged at the top of the support frame 1 along the travel direction of the wheel 12. The balance bar 2 is slidably arranged in the first adjustment cylinder 71, and the operator can adjust the position of the balance bar 2 in the first adjustment cylinder 71 according to actual needs to form a lever with different force arms. The first fastener is detachably arranged between the first adjustment cylinder 71 and the balance bar 2. After the position of the balance bar 2 is adjusted, the balance bar 2 and the support frame 1 can be fixedly connected together.

[0029] The clamping assembly 3 has two clamping arms hinged together in the middle, and rubber pads 5 are provided on the clamping surfaces opposite to each other at the lower ends of the two clamping arms. The upper ends of the clamping arms are arranged at the front end of the balance pole 2. The grip 4 is arranged at the rear end of the balance pole 2. When in use, the operator can adjust the height of the clamping assembly 3 by lifting and pressing the grip 4, and move the clamping assembly 3 close to the small prefabricated component to be transported, and clamp the two sides of the small prefabricated component through the two clamping surfaces at the lower end. Then, the clamping assembly 3 can be lifted by pressing the grip 4, and the small prefabricated component can be clamped by gravity. Subsequently, the small prefabricated component can be transported to the desired position by pushing the auxiliary trolley through the grip 4, and then the small prefabricated component can be put down by lifting the grip 4. With the help of the rubber pad 5 at the lower end of the clamping arm, the clamping wall can be prevented from causing damage to the small prefabricated component, and the friction between the clamping assembly 3 and the small prefabricated component can also be increased to prevent the small prefabricated component from falling during transportation.

[0030] In addition, in this embodiment, the balance bar 2 is slidably arranged in the first adjustment cylinder 71, and the operator can adjust the position of the balance bar 2 in the first adjustment cylinder 71 according to actual needs to form a lever with different force arms. For example, when the range of activities at the construction site is large, the length from the handle 4 to the first adjustment cylinder 71 can be made greater than the length from the clamping assembly 3 to the first adjustment cylinder 71, and when transporting small prefabricated components, labor-saving operation can be achieved, but the range of activities of the operator will be increased; when the range of activities at the construction site is small, the length from the handle 4 to the first adjustment cylinder 71 can be made less than the length from the clamping assembly 3 to the first adjustment cylinder 71, and when transporting small prefabricated components, the operator only needs a small range of activities to rotate the auxiliary trolley in place, thereby moving the small prefabricated components a large distance.

[0031] In addition, in this embodiment, a second adjusting cylinder 72 is slidably provided at the front end of the balance pole 2, and a second fastener is detachably provided between the second adjusting cylinder 72 and the balance pole 2. The upper end of the clamping arm is provided on the second adjusting cylinder 72, so the clamping arm can move back and forth on the balance pole 2 with the second adjusting cylinder 72, so that the operator can adjust the position of the clamping assembly 3 during actual use without adjusting the position of the entire auxiliary trolley, which makes it more convenient for users to lift small prefabricated components.

[0032] In addition, a third adjustment cylinder 73 is slidably provided at the rear end of the balance pole 2, a third fastener is detachably provided between the third adjustment cylinder 73 and the balance pole 2, and the handle 4 is fixed on the third adjustment cylinder 73. Therefore, the handle 4 can move forward and backward on the balance pole 2 along with the third adjustment cylinder 73, so that the operator can adjust the position of the handle 4 without adjusting the position of the entire auxiliary trolley during actual use, which is more convenient for users to lift small prefabricated components.

[0033] Further, in this embodiment, the first fastener is a fastening bolt threadedly connected to the side wall of the first adjustment cylinder 71; the second fastener is a fastening bolt threadedly connected to the side wall of the second adjustment cylinder 72; and the third fastener is a fastening bolt threadedly connected to the side wall of the third adjustment cylinder 73. By adjusting the depth of each fastening bolt on the adjustment cylinder, the inner end of the fastening bolt can be tightly pressed against the balance pole 2, which is convenient for the user to fix each adjustment cylinder on the balance pole 2. In other embodiments, existing connectors such as buckles and ferrules can also be used to realize the installation of each adjustment cylinder on the balance pole 2.

[0034] In addition, in this embodiment, more than two first fasteners are provided on the first adjustment cylinder 71, more than two second fasteners are provided on the second adjustment cylinder 72, and more than two third fasteners are provided on the third adjustment cylinder 73. This can improve the stability of the connection between each adjustment cylinder and the balance pole 2.

[0035] Furthermore, in this embodiment, a connecting chain 6 is provided between the upper end of the clamping arm and the second adjusting cylinder 72, and the connecting chain 6 is composed of a plurality of chain links. In actual application, the operator can adjust the length of the connecting chain 6 according to the size of the small prefabricated components to be transported, so as to facilitate the lifting of the small prefabricated components.

[0036] When transporting small prefabricated components, the small prefabricated components are prone to shaking, which in turn causes the second adjustment cylinder 72 to be loose on the balance pole 2, and in serious cases, the prefabricated components may fall. Therefore, in one embodiment, an anti-falling rope is further provided between the second adjustment cylinder 72 and the first adjustment cylinder 71, and the safety of transporting small prefabricated components is indirectly improved by means of the first adjustment cylinder 71.

[0037] In this embodiment, the support frame 1 has a vertically arranged telescopic rod 13, the upper end of which is fixedly connected to the first adjustment cylinder 71, and can adjust the height of the entire auxiliary trolley, so that it is suitable for transporting larger prefabricated components.

[0038] In addition, in this embodiment, the wheel 12 is detachably mounted on the axle 11, so that the operator can easily replace the wheel 12 of a suitable size according to the size of the prefabricated component. In addition, the tire surface of the wheel 12 is provided with a deep groove pattern, which can increase the friction coefficient of the tire, thereby making the auxiliary trolley suitable for slippery sites.

[0039] In addition, if Figure 2 As shown, a snap ring 81 is slidably mounted on the axle 11, and a clamping rod 82 extending toward one side of the wheel 12 is formed on one side of the snap ring 81. When necessary, the snap ring 81 can be slid to allow the clamping rod 82 to enter the middle of the wheel 12, thereby limiting the rotation of the wheel 12, making it convenient to temporarily fix the auxiliary trolley on a sloped site to ensure that the transportation of prefabricated components can proceed normally.

[0040] More specifically, in this embodiment, each adjustment cylinder is made of Q235 grade steel pipe, with a specification of φ60×3.2mm, and the length can be set according to actual needs. The handle 4 is made of natural rubber, with an inner diameter of 22mm and a thickness of 3mm. The handle 4 is connected by being sleeved on two steel pipes welded on both sides of the third adjustment cylinder 73, and is mainly used as a hand-held part during manual lifting and operation. The balance bar 2 is made of Q235 grade steel pipe, with a specification of φ48×3.2mm and a length of 3m. The main function of the balance bar 2 is to use the principle of leverage to lift, transport and install small prefabricated components. The ratio of its front and rear arm lengths can be adjusted according to the actual situation on site to adapt to the lifting and installation of small prefabricated components under different terrain conditions. The support frame 1 is made of Q235 grade steel pipe and adopts a triangular truss structure, which has the advantages of being firm and stable. Its function is to connect the balance bar 2 and the tire, and it is the main force-bearing structure of this device. The hub material of the wheel 12 is Q235 grade steel, the tread material is natural rubber, and the diameter is 70cm. The tire is a solid tire, which eliminates the hidden dangers of tire blowout and damage during load-bearing operation and in harsh working environments. The wheel 12 is connected to the axle 11 on the support frame 1 by an independent bearing. The main body of the clamping arm in the clamping assembly 3 is made of Q235 grade steel, and the clamping surface position adopts a polyurethane rubber pad 5, and the opening size is adjustable in three gears of 30-50cm. The overall structural form is "X" type, and self-balancing can be achieved by using the dead weight of small prefabricated components and the friction of the clamp. A rotatable lifting ring is used on the top of the clamp to achieve full-angle installation of small prefabricated components.

[0041] Compared with the traditional method of using thin iron wire to wrap small prefabricated components, then hoisting them to the installation position, and finally installing them in place through manual assisted adjustment and positioning. The clamping part of the clamping assembly 3 in the small prefabricated component installation auxiliary trolley adopts polyurethane rubber pad 5 to adopt soft contact with the small prefabricated components, which can effectively reduce the damage to the small prefabricated components and ensure the construction quality. The traditional hoisting method requires the use of thin iron wire to wrap small prefabricated components, and for installation sites that cannot be entered by mechanical equipment, they need to be manually transported to the installation site for installation. However, the small prefabricated component installation auxiliary trolley does not require complex connections, and can directly clamp the small prefabricated components, and as long as the site can be entered manually, the auxiliary trolley can enter the construction, effectively improving work efficiency. In addition, the small prefabricated component installation auxiliary trolley is cheap, has high utilization rate, and low damage rate. It can replace traditional loaders or forklifts, reduce mechanical investment, and effectively reduce construction costs. The small prefabricated component installation auxiliary trolley can replace manual transportation, effectively reducing the safety risks in construction operations.
