Description

Technical Field

[0001] The present invention relates to the field of construction equipment, and more specifically, to a cover plate construction auxiliary device. Background Art

[0002] Drainage channels are supporting projects for road, municipal and water conservancy construction. During the construction of drainage channels, it is first necessary to dig the ditch, then build the formwork, pour concrete to form the ditch body, and after the concrete solidifies, the prefabricated concrete ditch cover is installed on top of the ditch by manual transportation or crane.

[0003] Manual handling is time-consuming and labor-intensive, and a crane is required to lift the cover plate, which requires a large working space. In construction sites with limited space, it is not convenient for the crane to enter, so it is necessary to improve the ditch cover plate paving device. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a cover plate construction auxiliary device, which saves time and labor and has strong operability.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A cover plate construction auxiliary device comprises a transport frame and a gantry, wherein a transfer wheel is movably mounted on the bottom end of the gantry via a rotating shaft, and the gantry moves on the upper surface of the transport frame via the transfer wheel, a lifting screw rod is penetrated through the top end of the gantry, a C-shaped buckle is movably nested in the bottom end of the lifting screw rod, and a clamping screw rod is movably penetrated through the bottom end of the C-shaped buckle.

[0007] Furthermore, the outer side of the clamping screw is provided with a forward thread and a reverse thread, and a splint A is nested on the outer side of the clamping screw corresponding to the forward thread, and a splint B is nested on the outer side of the clamping screw corresponding to the reverse thread. The splint A and the clamping screw are screwed together through the forward thread, and the splint B and the clamping screw are screwed together through the reverse thread.

[0008] Furthermore, the lifting screw rod and the gantry are screwed together by means of threads, and the bottom end of the lifting screw rod passes through a limiting pin.

[0009] Furthermore, the top of the clamping plate A is provided with limiting ears on both sides, and the top of the clamping plate B is also provided with limiting ears on both sides.

[0010] Furthermore, an introduction wheel set is movably mounted on one end of the transport frame via a rotating shaft, and a balancing wheel is movably mounted on the other end of the transport frame via a rotating shaft.

[0011] Compared with the prior art, the advantages of the present invention are: This solution uses a transport frame to transport the ditch cover. A gantry is movably installed on the transport frame. A lifting screw rod runs through the center of the gantry. A clamping screw rod is installed at the bottom of the lifting screw rod. By rotating the clamping screw rod, the clamping plate A and the clamping plate B nested on the outside of the clamping screw rod are moved in an aligned manner to facilitate clamping the cover. After clamping the cover, the lifting screw rod is rotated to lift the cover, and then the transport frame is pushed horizontally above the ditch, so that the cover can be stably placed above the ditch, which saves time and effort and has strong operability.

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention. Example

[0015] See also Figure 1-Figure 8A cover plate construction auxiliary device includes a transport frame 101 and a gantry 102. A transfer wheel 121 is movably installed at the bottom end of the gantry 102 through a rotating shaft, and the gantry 102 moves on the upper surface of the transport frame 101 through the transfer wheel 121. A lifting screw rod 103 is penetrated at the top end of the gantry 102, and a C-shaped buckle 131 is movably embedded at the bottom end of the lifting screw rod 103. A clamping screw rod 105 is movably penetrated at the bottom end of the C-shaped buckle 131. This arrangement makes it easy to lift or lower the height of the clamping screw rod 105 through the lifting screw rod 103.

[0016] See also Figure 1-Figure 8 The outer side of the clamping screw 105 is provided with a forward thread 154 and a reverse thread 155, and a splint A151 is nested on the outer side of the clamping screw 105 corresponding to the forward thread 154, and a splint B152 is nested on the outer side of the clamping screw 105 corresponding to the reverse thread 155. The splint A151 and the clamping screw 105 are screwed together through the forward thread 154, and the splint B152 and the clamping screw 105 are screwed together through the reverse thread 155. In this way, when the clamping screw 105 is rotated, the splint B152 and the splint A151 can be driven by the reverse thread 155 and the forward thread 154 to move closer to or farther away from each other, so as to facilitate the clamping of the cover plate 109.

[0017] See also Figure 1-Figure 8 The lifting screw rod 103 and the gantry 102 are screwed together by threads, and the bottom end of the lifting screw rod 103 passes through the limiting pin 132. This arrangement makes it easy to lift the cover plate 109.

[0018] See also Figure 1-Figure 8 Limiting ears 153 are provided on both sides of the top of the clamping plate A151, and limiting ears 153 are also provided on both sides of the top of the clamping plate B152. This arrangement can prevent the clamping plates A151 and B152 from tilting.

[0019] See also Figure 1-Figure 8 One end of the transport frame 101 is movably mounted with an introduction wheel set 104 via a rotating shaft, and the other end of the transport frame 101 is movably mounted with a balance wheel 106 via a rotating shaft. This arrangement facilitates the transport frame 101 to roll and move to the top of the ditch 108. Example

[0020] Based on the first embodiment, the present invention changes the driving mode of the lifting screw 103 from manual to motor drive, which is more labor-saving.

[0021] When in use: first move the transport frame 101 to the top of the cover plate 109, then rotate the lifting screw rod 103 to lower the height of the clamping screw rod 105, and place the clamping plates A151 and B152 nested on the clamping screw rod 105 at both ends of the cover plate 109, and then rotate the clamping screw rod 105 to clamp the clamping plates A151 and B152 to lift the cover plate 109, and then rotate the lifting screw rod 103 to raise the height of the clamping screw rod 105, and then The cover plate 109 is lifted, and then the transport frame 101 is moved to above the foundation 107 and the ditch 108. The gantry 102 is then moved so that the gantry 102 is directly above the ditch 108. The lifting screw 103 is then rotated to lower the height of the cover plate 109. The clamping screw 105 is then rotated to move the clamp A 151 and the clamp B 152 away from each other. The cover plate 109 falls steadily on the upper surface of the ditch 108, and the paving operation of the cover plate 109 is completed.
