Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a cleaning tool for bolt sleeves. Background Art
[0002] At present, tension bolts are often used to reinforce the formwork during the construction of the main concrete structure. After the concrete pouring is completed and the formwork is removed, the end of the tension bolt sleeve remains outside the concrete component and needs to be cut off. The cleaning of the high bolt sleeve is generally carried out with an ordinary scraper tool. When cleaning the high bolt sleeve, this cleaning tool must first keep a certain distance between the scraper and the sleeve, and then the operator will aim the scraper at the sleeve, and the operator will use force to remove the sleeve. The above cleaning method has obvious disadvantages, it consumes a lot of time and manpower, and the operator often fails to control the force well, resulting in the accuracy deviation between the scraper and the sleeve, so the sleeve cannot be scraped, the cleaning efficiency is low, and the operator must raise both arms holding the rod above the head when operating this method, so it will be more laborious if the operation time is too long. Utility Model Content
[0003] The utility model aims to solve the problems existing in the prior art and provide a cleaning tool for bolt sleeves. By solving the problem of the force point, the scraper and the sleeve can achieve zero-distance scraping of the sleeve, thereby solving the problem of low accuracy.
[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0005] A bolt sleeve cleaning tool comprises a main rod, a scraper is provided at the front end of the main rod, a rear block is provided at the rear end of the main rod, a front block is provided at the rear of the main rod, a sleeve hammer is provided between the front block and the rear block, the sleeve hammer is sleeved on the main rod and slidably connected to the main rod, and the distance between the front block and the rear block is greater than the length of the sleeve hammer.
[0006] Preferably, the main rod is a round steel tube.
[0007] Preferably, the length of the main rod is adjustable.
[0008] Preferably, the scraper is a rectangular scraper or a trapezoidal scraper.
[0009] Preferably, a counterweight block is provided on the sleeve hammer.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] When the utility model is in use, the scraper is closely attached to the bolt sleeve to be cleaned, and the sleeve hammer repeatedly hits the front stopper, and the impact force of the sleeve hammer is transmitted to the scraper through the main rod, so that the sleeve is scraped off, which greatly increases the accuracy of sleeve cleaning; during operation, two arms only need to be placed at the waist and chest to operate, and the operator will be more relaxed and labor-saving; the force point is the sleeve hammer hitting the front stopper, the front stopper is welded to the main rod, and the main rod is welded to the scraper, and the impact force of the sleeve hammer hitting the front stopper is transmitted to the scraper through the main rod. By solving the problem of the force point, the scraper and the sleeve can achieve zero-distance scraping of the sleeve, thereby solving the problem of low accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a structural schematic diagram of the utility model.
[0013] Numbers in the attached figure: 1, main rod; 2, scraper; 3, rear block; 4, front block; 5, hammer. DETAILED DESCRIPTION
[0014] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0015] Embodiment 1: As attached Figure 1 As shown, the utility model is a bolt sleeve cleaning tool, comprising a main rod 1, a scraper 2 is provided at the front end of the main rod 1, a rear block 3 is provided at the rear end of the main rod 1, a front block 4 is provided at the rear of the main rod 1, a sleeve hammer 5 is provided between the front block 4 and the rear block 3, the sleeve hammer 5 is sleeved on the main rod 1 and slidably connected to the main rod 1, and the distance between the front block 4 and the rear block 3 is greater than the length of the sleeve hammer 5.
[0016] Preferably, the main rod 1 is a round steel tube, which is convenient for gripping and facilitating the processing of the hammer sleeve.
[0017] Preferably, the scraper blade 2 is a rectangular scraper blade or a trapezoidal scraper blade.
[0018] Preferably, a counterweight block is provided on the sleeve hammer 5 to increase the weight of the sleeve hammer 5 and improve the cleaning effect.
[0019] Specific:
[0020] The main rod 1 is a round steel tube with an outer diameter of 20 mm, and the total length of the main rod 1 can be determined according to needs;
[0021] The scraper blade 2 can be rectangular or trapezoidal, the rear end of the scraper blade 2 is welded to the front end of the main rod 1, the front end of the scraper blade 2 is a blade surface for scraping off the bolt sleeve, and the left side and / or right side of the scraper blade 2 is also a blade surface for cutting the sleeve;
[0022] The rear stopper 3 is a round steel tube with an inner diameter 2 mm larger than the outer diameter of the main rod 1 , which passes through the main rod 1 and is welded to the main rod 1 as a whole, so as to prevent the sleeve hammer 5 from falling off.
[0023] The front stopper 4 is a round steel tube with an inner diameter 2 mm larger than the outer diameter of the main rod 1, passing through the main rod 1 and being welded to the main rod 1 as a whole;
[0024] The distance between the rear stopper 3 and the front stopper 4 is 1000 mm;
[0025] The sleeve hammer 5 is 300mm long and is divided into two layers. The inner layer is made of a round steel pipe with an inner diameter 2mm larger than the outer diameter of the main rod, and the main rod 1 is passed through the inner layer. The outer layer is a steel bar straight thread sleeve with a larger outer diameter than the inner round steel pipe as a counterweight block welded with the inner round steel pipe to increase the weight. The main rod 1 passes through the center hole of the sleeve hammer 5.
[0026] The hammer 5 can move freely between the front stopper 4 and the rear stopper 3;
[0027] The front stopper 4 resists the impact of the casing hammer 5 to generate an impact force during operation, and the impact force is transmitted to the scraper 2 through the main rod 1, so as to achieve the purpose of scraping the casing.
[0028] When operating, the staff holds the main rod 1 in one hand and the hammer 5 in the other hand, so that the scraper 2 is in close contact with the tension bolt casing to be cleaned; the arm holding the hammer 5 is withdrawn, and then the arm holding the hammer 5 exerts force to make the hammer 5 hit the front block 4; the impact force of the hammer 5 and the front block 4 drives the main rod 1 to make the scraper 2 rush forward, thereby removing the tension bolt casing.
[0029] Embodiment 2: This embodiment further improves the main rod member on the basis of Embodiment 1. The length of the main rod member 1 is adjustable. Specifically, the main rod member 1 adopts a multi-section structure. The main rod member 1 includes a plurality of rod units connected in sequence. A scraper 2 is welded to the front end of the front end rod unit. The hammer 5, the front block 4 and the rear block 3 are all arranged on the rear end rod unit. The number of middle rod units can be set according to usage needs. The front and rear rod units are connected by threads. The rear ends of the rod units are provided with threaded holes, and the front ends of the middle rod unit and the rear end rod unit are provided with threaded columns. The length of the main rod member 1 can be adjusted by adjusting the number of middle rod units. It can be suitable for cleaning bolt sleeves of different heights.
