Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting dust removal equipment, and in particular to a multifunctional intelligent fire-fighting dust-raising tower crane. Background Art

[0002] Tower crane is a common lifting equipment that solves the material supply problem of high-altitude operations. It can rotate to a large extent and cover a wide area. It is widely used in construction sites and is also an indispensable equipment for the construction of high-rise buildings.

[0003] On construction sites, the use of a large number of powdered materials such as cement, fly ash, and mineral powder causes serious dust pollution on the sites. In addition, since there are many flammable materials and electrical facilities on the sites, there are safety hazards of fire. Once the fire point is at a high position, ordinary fire extinguishing equipment cannot meet the requirements, and fire trucks take a certain amount of time to arrive, and often cannot effectively extinguish the fire when the burning area is small. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a multifunctional intelligent fire-fighting dust-raising tower crane. After a fire occurs, the tower crane driver can immediately operate the tower crane to extinguish the fire, thereby ensuring the timeliness of the fire extinguishing.

[0005] The present invention is achieved through the following technical scheme, which provides a multifunctional intelligent fire-fighting dust-raising tower crane, including a tower body and a lifting arm, on which a nozzle moving along the length direction is installed, and the nozzle is connected to a water supply device.

[0006] When the present solution is in use, the water provided by the water supply device is sprayed out through the nozzle to extinguish the fire. By utilizing the rotation of the crane arm and the movement of the nozzle along the length direction, the nozzle is aimed at the fire point to spray and extinguish the fire, thereby achieving targeted fire extinguishing and improving the fire extinguishing efficiency. In addition, the water sprayed by the nozzle can also be used to maintain the wall.

[0007] As an optimization, the water supply device includes a water pipe connected to the nozzle at one end, a reel wound around the water pipe, and a high-pressure water pump connected to a water source. The other end of the water pipe is connected to the inner cavity of the reel. One end of the reel is connected to the water supply pipe through a rotary joint. The end of the water supply pipe away from the reel is connected to the high-pressure water pump. This optimization scheme uses a high-pressure water pump to pump water to meet the water supply requirements. When the nozzle moves away from the reel, the water pipe pulls the reel to rotate to unwind the water pipe. When the nozzle moves toward the reel, the water pipe is wound and stored by rotating the reel, thereby ensuring the orderly retraction and release of the water pipe and avoiding interference with the wire rope of the lifting part.

[0008] As an optimization, the drum is provided with a first winding part and a second winding part distributed along the axial direction, the water pipe is wound around the first winding part, the second winding part is wound with a pull rope, a fixed pulley is installed on the boom and is located on the side of the nozzle away from the drum, and one end of the pull rope extends out of the drum and passes around the fixed pulley to connect with the nozzle. This optimization scheme winds the water pipe and the pull rope on the same drum, and through the redirection effect of the fixed pulley, when the drum rotates forward, the pull rope pulls the nozzle to move, and the water pipe is unwound at the same time, meeting the nozzle movement requirements. When the drum rotates in the opposite direction, the water pipe is used to pull the nozzle to move, and the water pipe is wound around the drum to achieve reeling, while the pull rope is unwound at the same time, meeting the nozzle movement requirements and improving the flexibility of nozzle movement.

[0009] As an optimization, a slide rail extending along the length direction is fixedly connected to the top beam of the crane arm, and a sliding frame fixedly connected to the nozzle is slidably connected to the slide rail. This optimization scheme improves the stability of the nozzle movement by setting the slide rail, avoids the nozzle from sagging at a distance from the reel, and avoids interference with the lifting part.

[0010] As an optimization, the slide rail includes a vertical plate fixed to the bottom surface of the top beam of the boom and a horizontal plate fixed to the bottom of the vertical plate. The horizontal plates on both sides of the vertical plate are provided with rollers rotatably connected to the sliding frame. The slide rail structure of this optimization scheme is convenient for connecting with the top beam of the boom by setting the vertical plate, and the flexibility of the movement of the sprinkler is improved by setting the rollers. The rollers are set on both sides of the vertical plate to improve the stability of the movement of the sprinkler.

[0011] As an optimization, the water supply pipe includes a plurality of short water supply pipes fixedly connected to the tower body standard section and having a length less than or equal to the length of the tower body standard section, and adjacent short water supply pipes are connected via quick-connect connectors. This optimization scheme sets the water supply pipe as a plurality of short water supply pipes, fixes each short water supply pipe on the tower body standard section, and after the tower body standard section is installed, the adjacent short water supply pipes are connected via quick-connect connectors, thereby improving the convenience of installation and construction.

[0012] As an optimization, a dust removal water pipe connected to the water supply device is fixed on the bottom beam of the crane arm, and a plurality of sprinkler heads are arranged on the dust removal water pipe along the length direction. This optimization scheme sprinkles water on the construction site by setting up dust removal water pipes and sprinkler heads, which can prevent dust and reduce the temperature, thereby improving the safety of construction operations.

[0013] As an optimization, the dust removal water pipe includes a plurality of dust removal short pipes respectively fixed to the boom unit section and having a length less than or equal to the length of the boom unit section, and adjacent dust removal short pipes are connected via quick-connect connectors. This optimization scheme configures the dust removal water pipe as a multi-section dust removal short pipe, and integrates the dust removal short pipe into the boom unit section, thereby improving installation efficiency.

[0014] As an optimization, it also includes a controller electrically connected to the water supply device, and an online dust monitor electrically connected to the controller. This optimization solution detects the dust on the construction site through the online dust monitor set up, and transmits the detection signal to the controller. If the dust content exceeds the set value, the controller sends a signal to the tower crane driver or sends an opening instruction to the water supply device to perform dust removal operations, thereby improving the timeliness and automation of dust removal.

[0015] As an optimization, a temperature sensor electrically connected to the controller is installed on the boom. This optimization solution detects the temperature through the set temperature sensor and transmits the signal to the controller. If the temperature exceeds the set value, the controller starts the water supply device to extinguish the fire, thus achieving fire extinguishing in the early stage, preventing the fire from developing and reducing losses.

[0016] The beneficial effects of the present invention are as follows: utilizing the height advantage of the tower crane to spray water from top to bottom to extinguish the fire, and once a fire occurs, it is easy to be observed by the tower crane driver, so the tower crane can be immediately operated to extinguish the fire, thereby ensuring the timeliness of the fire extinguishing, and by moving the nozzle, fixed-point fire extinguishing is achieved, thereby improving the fire extinguishing efficiency; utilizing the water sprayed by the sprinkler pipe to remove dust and reduce the temperature, thereby improving the construction environment of the construction site and being beneficial to ensuring the health of the construction workers; and it can also be used for the maintenance of cement construction surfaces, thereby reducing labor and improving the maintenance efficiency.

[0024] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0025] like Figure 1 A multifunctional intelligent fire-fighting dust-raising tower crane is shown, comprising a tower body 1, a lifting arm 4 and a water supply device. The tower body comprises a number of standard tower body sections fixed in sequence, the lifting arm comprises a number of lifting arm unit sections fixed in sequence, and the structure of the lifting part of the tower crane adopts the existing technology.

[0026] A nozzle 12 is installed on the lifting arm 4 and moves along the length direction. The nozzle 12 is a high-pressure nozzle. The nozzle is connected to a water supply device. The spray end of the nozzle is set downward and staggered with the wire rope of the lifting part to prevent the wire rope from obstructing the spraying water.

[0027] The water supply device includes a water pipe 13, a drum 14, a motor 15, a high-pressure water pump 6 and a water supply pipe 5. The high-pressure water pump 6 is an intelligent variable-frequency high-pressure water pump. Since the cross-section of the lifting arm is a triangular structure formed by a top beam and two bottom beams, in order to avoid interference, the drum 14, the motor 15 and the nozzle are all located at the upper part of the triangle, above the wire rope of the lifting part and the sliding vehicle. The water outlet of the water pipe 13 is connected to the nozzle through a thread, the water inlet of the water pipe 13 is connected to the inner cavity of the drum, the water pipe is wound on the drum 14, one end of the drum is fixedly connected to a transmission core shaft connected to the motor 15, the other end of the drum is fixedly connected to a hollow shaft coaxial with the transmission core shaft, the hollow shaft is connected to the inner cavity of the drum, the transmission core shaft and the hollow shaft are respectively installed on the crane arm through seat bearings; the high-pressure water pump is arranged on one side of the bottom of the tower body, the water inlet of the high-pressure water pump 6 is connected to the water source, and the water outlet is connected to the water supply pipe 5, the upper end of the water supply pipe 5 is connected to the hollow shaft through a rotary joint 16, the rotary joint adopts the existing technology, by setting the rotary joint, when the drum rotates, the water supply pipe remains stationary and supplies water to the inner cavity of the drum. The water supply pipe includes a number of water supply short pipes fixedly connected to the standard section of the tower body and having a length less than or equal to the length of the standard section of the tower body, and adjacent water supply short pipes are connected through quick plug connectors.

[0028] In order to improve the flexibility of the movement of the nozzle, the drum of this embodiment is provided with a first winding part and a second winding part distributed along the axial direction, and a baffle fixed to the drum is arranged between the first winding part and the second winding part. The water pipe 13 is wound on the first winding part, and the second winding part is wound with a pull rope 11. The boom is equipped with a fixed pulley 10 located on the side of the nozzle away from the drum. One end of the pull rope extending out of the drum passes around the fixed pulley and is connected to the nozzle. When the motor drives the drum to rotate, the water pipe and the pull rope cooperate with each other to ensure the flexible movement of the nozzle, wherein the fixed pulley is rotatably connected to a bracket fixed to the top beam of the boom.

[0029] A slide rail 8 extending in the length direction is fixedly connected to the boom top beam 7, and a sliding frame 9 fixed to the nozzle is slidably connected to the slide rail. The slide rail includes a vertical plate 17 fixed to the bottom surface of the boom top beam 7 and a horizontal plate 18 fixed to the bottom of the vertical plate. Rollers 19 rotatably connected to the sliding frame are slidably arranged on the horizontal plates on both sides of the vertical plate.

[0030] A dust removal water pipe 2 connected to the water supply device is fixedly connected to the bottom beam of the boom, and a plurality of spray heads 3 distributed along the length direction are arranged on the dust removal water pipe 2. The dust removal water pipe includes a plurality of dust removal short pipes respectively fixed to the boom unit sections and having a length less than or equal to the length of the boom unit section, and adjacent dust removal short pipes are connected through quick-connect connectors.

[0031] In order to improve the automation level and timeliness of fire extinguishing and dust removal, the present embodiment also includes a controller 20 electrically connected to the high-pressure water pump of the water supply device, and an online dust monitor for the construction site electrically connected to the controller. A temperature sensor electrically connected to the controller is installed at the bottom of the bottom beam of the crane arm. The online dust monitor for the construction site is used to detect the dust content of the surrounding environment, and the temperature sensor is used to detect the temperature. The controller receives signals from the online dust monitor for the construction site and the temperature sensor, and controls the opening and closing of the high-pressure water pump according to the dust content and temperature. The structures of the temperature sensor, the online dust monitor for the construction site and the controller adopt the existing technology, and the connection between the three is also realized by the existing technology.

[0032] During the operation of the tower crane, if a fire occurs, the tower crane driver can easily observe the fire location because he is at a high place. By controlling the rotation of the crane arm and the movement of the nozzle, the nozzle is located above the fire point, and the fire is extinguished by starting the high-pressure water pump to supply water. The water sprayed by the sprinkler pipe cools the surrounding area and plays a role in assisting fire extinguishing. If the temperature signal received by the controller is greater than or equal to the set temperature, the high-pressure water pump is automatically started to cool down. When the received temperature signal is less than the set temperature, the high-pressure water pump is turned off to avoid waste. If the dust content is higher than the set value, the controller starts the high-pressure water pump for dust removal, thereby achieving timeliness of fire extinguishing and dust removal.
