Description
Technical Field
[0001] The present application relates to the technical field of construction auxiliary tools, and in particular to an I-beam crowbar. Background Art
[0002] A crowbar is a kind of labor tool, which usually uses the principle of lever to make heavy objects overcome gravity, so as to achieve the effect of lifting heavy objects from the ground and producing displacement. Crowbars are divided into hexagonal bars, round bars and flat crowbars. Hexagonal bars and round bars are usually processed into double round heads, double flat heads or one round head and one flat head, etc., and are mostly used as construction tools or hardware tools. Flat crowbars are mostly used as tire repair tools on vehicles or for railway track inspection and maintenance.
[0003] A truss is a supporting beam structure formed by connecting I-beams and other rods through welding, riveting, threaded connections, etc. In the construction field, spatial structures such as roof trusses or bridges are composed of a series of parallel plane trusses. An I-beam generally includes an upper plate, a lower plate, and a beam vertically arranged between the upper and lower plates. The upper and lower plates are parallel to each other and it is a long strip of steel with an I-shaped cross-section.
[0004] The assembly of a truss usually involves welding several parallel I-beams to the frame, inserting the flat end of a crowbar into the gap between the I-beam to be welded and the truss, and dragging the crowbar to adjust the position of the I-beam on the truss. However, due to the lack of fixation between the end of the crowbar and the I-beam, the I-beam is prone to tipping over during the dragging of the crowbar. At this time, the I-beam needs to be straightened and the welding position readjusted, which is a cumbersome process and reduces the efficiency of truss assembly. Utility Model Content
[0005] In order to improve the situation where the I-beam falls over on the truss when the crowbar is dragged, and to improve the assembly efficiency of the truss, the present application provides an I-beam crowbar.
[0006] The I-beam crowbar provided in this application adopts the following technical solution:
[0007] A crowbar for an I-beam comprises a crowbar body, a prying block and a clamping block, wherein the prying block is arranged on the outer wall of one end of the crowbar body, the clamping block is slidably installed on the outer wall of the crowbar body and is arranged adjacent to the prying block, and a clamping gap is formed between the clamping block and the prying block for clamping and fixing the I-beam.
[0008] By adopting the above technical solution, the main body of the crowbar provides an installation platform for the prying block and the clamping block. The prying block is arranged on the end of the main body of the crowbar, inserted between the I-beam and the truss, and has a limiting effect on the I-beam. The clamping block is arranged adjacent to the prying block and forms a clamping gap with the prying block, so that the I-beam can be clamped and fixed between the prying block and the clamping block. The clamping block slides on the main body of the crowbar to facilitate adjustment of the width of the clamping gap, thereby improving the clamping stability of the clamping block and the prying block on the I-beam, preventing the I-beam from tipping over on the truss when the crowbar drags the I-beam, thereby improving the assembly efficiency of the truss.
[0009] Optionally, a sliding block is provided on one end of the clamping block, a sliding cavity for the sliding block to slide is provided inside the crowbar body, a sliding groove for the clamping block to pass through and slide is provided on the outer wall of the crowbar body, the sliding groove and the sliding cavity are connected to each other, and one end of the clamping block away from the sliding block protrudes from the crowbar body and slides in the sliding groove.
[0010] By adopting the above technical solution, the sliding block is installed at the end of the clamping block. The sliding block slides inside the crowbar body to achieve the effect of driving the clamping block to slide on the crowbar body. The sliding block drives the clamping block to approach or move away from the prying block, changing the width of the clamping gap, so that the crowbar and the I-beam are more adapted, thereby improving the clamping stability of the clamping block and the prying block on the I-beam, preventing the I-beam from tipping over on the truss when the crowbar drags the I-beam, thereby improving the assembly efficiency of the truss.
[0011] Optionally, a lead screw for controlling the sliding of the slider is passed through the interior of the crowbar body, the lead screw passes through the slider and is threadedly connected to the outer wall of the lead screw and the sliding block, a toggle block is provided at the end of the lead screw, and a toggle groove for the toggle block to pass through is opened on the crowbar body.
[0012] By adopting the above technical solution, the setting of the lead screw can control the sliding of the sliding block in the crowbar body. The outer wall of the lead screw is threadedly connected to the slider. The sliding block can be driven to slide inside the crowbar body by rotating the lead screw through the toggle block, thereby achieving the effect of driving the clamping block to slide, making the crowbar and the I-beam more compatible, thereby improving the clamping stability of the clamping block and the prying block on the I-beam, preventing the I-beam from tipping over on the truss when the crowbar drags the I-beam, thereby improving the assembly efficiency of the truss.
[0013] Optionally, the clamping block is detachably connected to the sliding block.
[0014] By adopting the above technical scheme, the clamping block is used to cooperate with the prying block to clamp and pry the I-beam, which may easily cause the clamping block to wear. The clamping block and the slider are detachably connected, which can facilitate the replacement of the clamping block, thereby improving the clamping stability of the clamping block and the prying block on the I-beam, preventing the I-beam from tipping over on the truss when the crowbar drags the I-beam, thereby improving the assembly efficiency of the truss.
[0015] Optionally, the clamping block gradually narrows from an end connected to the sliding block to an end away from the sliding block.
[0016] By adopting the above technical solution, the clamping block is gradually narrowed from one end connected to the sliding block to the end away from the sliding block, so that the clamping block can stably clamp and fix the I-beam, preventing the I-beam from tipping over on the truss when the crowbar drags the I-beam, thereby improving the assembly efficiency of the truss.
[0017] Optionally, a slot for the I-beam to be clamped into is formed on one end of the clamping block away from the sliding block.
[0018] By adopting the above technical solution, the clamping groove on the clamping block is opened, so that the clamping block can clamp and fix the I-beam crossbeam, improve the stability of the crowbar when prying the I-beam, prevent the I-beam from tipping over, and thus improve the assembly efficiency of the truss.
[0019] Optionally, the prying block gradually narrows from an end connected to the crowbar body to an end away from the crowbar body.
[0020] By adopting the above technical solution, the prying block is gradually narrowed from the end connected to the crowbar body to the end away from the crowbar body, which makes it easy for the prying block to be inserted between the truss and the I-beam to pry the I-beam, which is beneficial to improving the stability of the crowbar when prying the I-beam and preventing the I-beam from tipping over, thereby improving the assembly efficiency of the truss.
[0021] Optionally, an arc-shaped guiding surface for prying the I-beam is provided at the connection position between the prying block and the crowbar body.
[0022] By adopting the above technical solution, the setting of the arc-shaped guide surface is equivalent to setting a fulcrum for the crowbar at the position of the arc-shaped guide surface, so that the crowbar can pry the I-beam more labor-saving, which is beneficial to improving the stability of the crowbar when prying the I-beam and preventing the I-beam from tipping over, thereby improving the assembly efficiency of the truss.
[0023] Optionally, the crowbar body gradually narrows at one end away from the prying block.
[0024] By adopting the above technical solution, the end of the crowbar body away from the prying block is gradually narrowed. When only fine-tuning is required between the I-beam and the truss, the end of the crowbar body away from the prying block can be used as an auxiliary pushing tool.
[0025] Optionally, an anti-slip sleeve is provided on the outer side wall of the crowbar body.
[0026] By adopting the above technical solution, the provision of the anti-slip sleeve can increase the friction of the user holding the crowbar, so that the user can pry the I-beam stably and prevent the I-beam from tipping over, thereby improving the assembly efficiency of the truss.

The clamping block is set adjacent to the prying block and forms a clamping gap with the prying block, so that the I-beam can be clamped and fixed between the prying block and the clamping block. The clamping block slides on the crowbar body to adjust the width of the clamping gap;
[0029] 2. The setting of the lead screw can control the sliding of the sliding block in the crowbar body.
