Description

Technical Field

[0001] This utility model relates to the field of flue gas duct auxiliary installation technology, and in particular to a flue gas duct handling and hoisting trolley that is easy to operate and carry. Background Technology

[0002] A flue is a tubular device for emitting exhaust gas and smoke. Residential flues refer to vertical pipe products used to exhaust kitchen fumes or bathroom fumes; they are also called ventilation ducts, air ducts, or residential exhaust ducts. Existing flues are all prefabricated and assembled according to the design requirements after the main building construction is completed. Since flues are generally made of cement concrete combined with reinforcing ribs and other components, they are relatively long and heavy. During installation, multiple teams are needed for handling and hoisting operations. Due to the installation inside the building, the handling and hoisting of flues are inconvenient due to the limited building space, which seriously affects the installation efficiency and quality and increases the construction difficulty for the installation operators. Therefore, a portable and easy-to-operate flue handling and hoisting trolley is proposed. Utility Model Content

[0005] The main body includes a column, a U-shaped connecting frame fixed to the bottom of the column, a traveling wheel rotatably connected to the inner side of the connecting frame, a crossbar installed on one side of the column, a support rod fixed to the bottom of the other end of the crossbar, a diagonal brace fixed to the top of the crossbar, a crossbeam parallel to the crossbar and fixed to the top of the column fixed to the other end of the diagonal brace, and an mounting plate connected to the suspension mechanism fixed to the top of the crossbeam.

[0006] The suspension mechanism includes a support plate connected to the mounting plate. A pulley and a guide wheel are connected to the top of the support plate via a bearing seat. A channel runs through the support plate. A traction rope connected to a hand-cranked winch is slidably connected to the outer ring of the pulley. A hook is installed at one end of the traction rope that extends out of the channel.

[0007] As a further improvement to the above solution, the bottom of the support rod is equipped with swivel casters, and the swivel casters have foot brakes.

[0008] As a further improvement to the above solution, a material feeding box with an opening at the top is installed on one side of the crossbar.

[0009] As a further improvement to the above solution, the lifting mechanism includes a support plate, with U-shaped placement plates abutting against the bottom of both sides of the support plate, and the placement plates are fixedly connected to the adjacent connecting frame or support rod.

[0010] As a further improvement to the above solution, the outer ring of the tray is covered with a ring-shaped rubber buffer layer.

[0011] As a further improvement to the above solution, the lifting mechanism is provided in two sets, one set is located between the two sets of connecting frames on the side that are close to each other, and the other set is located between the two sets of support rods.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example 1:

[0021] Please combine Figures 1-2 This embodiment of a flue gas duct transport and hoisting trolley that is easy to operate and carry includes two sets of parallel main bodies 1, a suspension mechanism connected between the tops of the two sets of main bodies 1, a lifting mechanism 4 connected between the two sets of main bodies 1, and a hand-cranked winch 3 connected to the suspension mechanism installed on the side of one of the main bodies 1 away from the lifting mechanism 4.

[0022] The main body 1 includes a column 11, a U-shaped connecting frame 12 fixed to the bottom of the column 11, a traveling wheel 13 rotatably connected to the inner side of the connecting frame 12, a crossbar 14 installed on one side of the column 11, a support rod 15 fixed to the bottom of the other end of the crossbar 14, a diagonal brace 16 fixed to the top of the crossbar 14, a crossbeam 17 parallel to the crossbar 14 and fixed to the top of the column 11 fixed to the other end of the diagonal brace 16, and a mounting plate 18 connected to the suspension mechanism fixed to the top of the crossbeam 17. The mounting plate 18 is fixed to the bearing plate 21 by bolts and nuts.

[0023] The suspension mechanism includes a support plate 21 connected to the mounting plate 18. The top of the support plate 21 is connected to a pulley 22 and a guide wheel 23 via a bearing seat. The support plate 21 has a channel 24 running through it. The outer ring of the pulley 22 is slidably connected to a traction rope 25 connected to a hand-cranked winch 3. A hook is installed at one end of the traction rope 25 that extends out of the channel 24.

[0024] Example 2:

[0025] The bottom of the support rod 15 is equipped with swivel casters, and the swivel casters have foot brakes;

[0026] A material feeding box with an opening at the top is installed on one side of the crossbar 14;

[0027] The lifting mechanism 4 includes a support plate 41, with U-shaped placement plates 42 abutting against the bottom of both sides of the support plate 41, and the placement plates 42 are fixedly connected to the adjacent connecting frame 12 or support rod 15.

[0028] The outer ring of the tray 41 is covered with a ring-shaped rubber buffer layer.

[0029] The lifting mechanism 4 is provided in two sets. One set is located between the two sets of connecting frames 12 on the side that are close to each other, and the other set is located between the two sets of support rods 15.

[0030] Working principle:

[0031] When hoisting the flue gas duct, first use the binding straps to bind the flue gas duct in the middle of the flue gas duct. Then push the hoisting trolley to the position of the flue gas duct, use the hand winch 3 to move the hook downward, then hang the binding strap on the hook, use the hand winch 4 to move the hook upward, thereby lifting the flue gas duct upward. When the flue gas duct is lifted off the ground, the flue gas duct is in an upward tilted state, and the flue gas duct can be moved in a narrow area by using a vertical pushing method.

[0032] When the handling space is too low to be used for vertical tilting, first use the above method to hang the flue gas duct, then lift the flue gas duct upward from the lower end of the back of the flue gas duct, then place the pallet 41 in the placement plate 42 on the connecting frame 12 and the support rod 15, and then move the flue gas duct downward to place it on the two sets of pallets 41. At this time, the flue gas duct is in a horizontal flat state, and the handling space is too low for handling.

[0033] During transport, the hoisted flue can be lifted and pushed forward by first raising the front end, and then lowered and raised the rear end to move it from a narrow position. This method is suitable for transporting flues in different spaces.

[0034] When not in use, the bearing plate 21 on the suspension mechanism is removed from the mounting plate 18, so that the two main bodies 1 are connected, which makes it easy to fold and store the two main bodies 1, and facilitates subsequent transportation and storage.

[0035] This utility model enables vertical hoisting and horizontal adjustment of flue gas ducts, facilitating their handling and installation in various environments. It reduces the difficulty of flue gas duct handling and installation, lowers the labor intensity of installers, and increases the efficiency of flue gas duct handling and installation. Furthermore, the simple and stable structure of the hoisting trolley facilitates adjustment, allowing operators to easily control the handling status of the flue gas duct and improve operational efficiency. The design employs a disassembly and assembly method, allowing for easy assembly during use and disassembly when not in use, thus facilitating transportation and storage.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
