Description

Technical Field

[0001] This utility model relates to the field of building engineering installation technology, specifically to a tool for short-distance transportation and labor-saving installation of radiators. Background Technology

[0002] With the development of society and the economy, heating equipment such as radiators has become an essential function of buildings. Radiators are mostly metal products, which are heavy and require multiple people to work together to install them on the wall. Furthermore, after the radiators are transported to the floor, there is still a certain distance between the centralized storage area and the installation location, which also requires multiple people to work together. This results in a large amount of labor consumption, low installation efficiency, and easy damage to the radiators from bumps and knocks. Utility Model Content

[0022] Please see Figure 1-9 This utility model discloses a tool for short-distance transportation and labor-saving installation of radiators. The tool includes five parts: a transport frame 1, a hanging frame 3, a transmission mechanism 6, a pressure rod 4, and a reversing limit mechanism 5.

[0023] The transport frame 1 is the main load-bearing structure of the tool, specifically comprising a bottom frame 1.6, a vertical frame 1.2, and a top frame 1.1, welded together to form a rectangular structure. The bottom frame 1.6 is a flat plate structure composed of multiple welded steel pipes, with casters 1.4 mounted on its bottom surface, allowing the entire structure to move in two directions on the ground. A limiting support frame 1.5 is welded to the middle of the upper surface of the bottom frame 1.6. The limiting support frame 1.5 consists of two L-shaped rods arranged in pairs, with a reversing limiting mechanism 5 installed on the rear side of the upper middle part of the two L-shaped rods. A circular hole is opened at the top of the limiting support frame 1.5, and a bearing is installed inside the hole. The bearing supports the transmission mechanism 6 but does not restrict its rotation. The vertical frame 1.2 is a C-shaped rod, which supports the top frame 1.1 and serves as a track for the vertical movement of the hanger. Drive shaft support seats 1.3 are welded to the outer sides of both sides of the vertical frame 1.2 for mounting the drive shaft 6.2.

[0024] The hanging bracket 3 comprises an upper crossbeam 3.1, a lower crossbeam 3.5, and two vertical support rods 3.3 welded together, forming a rectangular frame. Rollers 3.2 are installed at both ends of the upper crossbeam 3.1 and the lower crossbeam 3.5. The rollers 3.2 engage with the vertical frame 1.2 of the transport frame 1, reducing resistance during the vertical movement of the hanging bracket 3. A rack 3.4 is installed on the front side of the vertical support rod 3.3, which, driven by the transmission gear 6.1 of the transmission mechanism 6, causes the hanging bracket 3 to move up and down. The upper crossbeam 3.1 has long, open slots on its front and rear sides for installing temporary hooks 2 for radiators. The slots allow for adjustment of the spacing of the temporary hooks 2 to accommodate radiators of different lateral dimensions. The temporary hook 2 is a horizontal L-shaped rod. The long rod L of the L-shape passes through the long groove from back to front and is connected to the long rod on the front side with a nut. The part of the long rod of the L-shape other than the rear side of the upper crossbeam 3.1 is welded with an inverted L-shaped pad. The upper short side of the inverted L-shaped pad can hook the upper edge of the upper crossbeam 3.1, restricting the rotation of the temporary hook 2.

[0025] The transmission mechanism 6 includes a horizontally positioned transmission shaft 6.2. A drive gear 6.3 is mounted in the middle of the transmission shaft 6.2, and a transmission gear 6.1 is mounted at each end of the transmission shaft 6.2. Each transmission gear 6.1 has a bearing 6.4 mounted on its outer end outside the transmission shaft 6.2. The drive gear 6.3 is rotatably mounted between the two L-shaped rods of the limiting support frame 1.5. The teeth of the drive gear 6.3 are semi-circular arc-shaped and face the same direction. Its function is to transmit the torque applied by the pressure rod 4, which drives the transmission gear 6.1 to rotate via the transmission shaft 6.2. When the drive gear 6.3 rotates forward, the outer semi-circular arc surface of the teeth of the drive gear 6.1 contacts the arc surface of the brake rod 5.4 in the reversing limiting mechanism 5. The counterweight 5.3 and the brake rod 5.4 rotate and lift, not restricting the forward rotation of the drive gear 6.3. When the transmission shaft 6.2 reverses, the teeth of the drive gear 6.3 press against the brake rod 5.4, preventing the reversal and simultaneously preventing the hanger 3 from falling.

[0026] The reversing limiting mechanism 5 includes a support frame 5.2, two connecting pieces 5.1, a counterweight 5.3, a brake rod 5.4, and a limiting rod 5.5. The support frame 5.2 has an L-shaped structure. The connecting pieces 5.1, counterweight 5.3, and brake rod 5.4 are welded together to form a U-shaped whole. The limiting rod 5.5 is welded to the outer side of the bottom of this U-shaped whole. The ends of the two arms of the U-shaped whole, i.e., the ends of the two connecting pieces 5.1, are rotatably connected to the L-shaped support frame 5.2 via pins. The outer surface of the brake rod 5.4 is a quarter-circular arc. When the drive gear 6.3 rotates forward, the outer semi-circular surface of the teeth of the drive gear 6.3 contacts the arc surface of the brake rod 5.4, causing the counterweight 5.3 and the limiting rod 5.5 to rotate and lift, thus not restricting the forward rotation of the drive gear 6.3. The function of the limit rod 5.5 is to prevent the drive gear 6.3 from reversing when the drive gear 6.3 reverses. The teeth of the limit rod 5.5 press against the brake rod 5.4, and the limit rod 5.5 presses against the L-shaped support.

[0027] The pressure lever 4 includes a handle 4.1, a U-shaped plug 4.3 located at the front end of the handle 4.1, and a stop bar 4.2 horizontally welded inside the U-shaped plug 4.3. The U-shaped plug 4.3 can be inserted into both sides of the drive gear 6.3 and lock the drive shaft 6.2. When the pressure lever 4 is fully inserted, the stop bar 4.2 can engage the inner side of the teeth of the drive gear 6.3. When the pressure lever 4 is pressed down, the downward force can be converted into the rotation of the drive gear 6.3, causing the bracket 3 to rise.

[0028] The tool is used as follows: First, lift the reversing limit mechanism 5 to lower the hanger 3 to the appropriate position. Hang the radiator 7 on the temporary hook 2. Push the transport frame 1 to transport the radiator 7 to the required position. Insert the pressure rod 4 into both sides of the drive gear 6.3, so that the stop 4.2 of the pressure rod 4 hooks onto the inner side of the teeth of the drive gear 6.3. Press down the rear end of the handle 4.1. The drive gear 6.3 drives the transmission gear 6.1 to rotate, pulling the rack 3.4 upward. The hanger 3 carries the radiator 7 upward. If the radiator 7 does not rise to the correct position after one press, pull out the pressure rod 4.1 appropriately, hook onto the subsequent teeth of the drive gear 6.3, and repeat the pressing action. Before pulling out the pressure rod 4, the teeth of the drive gear 6.3 should be pressed against the brake rod 5.4 of the reversing limit mechanism 5 so that the drive gear 6.3 does not reverse and the radiator 7 does not fall. When the radiator 7 rises to a height higher than the wall mounting point, pull out the pressure rod 4, push the transport frame 1 close to the wall, so that the wall mounting point is inserted into the appropriate position of the radiator 7, lift the reverse limit mechanism 5, the bracket 3 and the radiator 7 descend, the radiator 7 is hung on the wall mounting point and disengaged from the temporary hook 2 of the bracket 3, at this time the tool can be removed and the next radiator can be installed.
