Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically a safe construction platform for water conservancy construction. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. During the construction of water conservancy projects, the construction platform is a relatively important piece of equipment, which can help workers to carry out construction better.

[0003] While existing construction platforms can be raised and lowered, and the lifting platform has side supports around it to protect operators, in actual use, when the platform sways during the lifting process, personnel may lose their balance and stumble at the top of the platform, potentially colliding with the side support plates and causing injury. In severe cases, the side support plates may be damaged, causing personnel to fall to the ground and resulting in even greater casualties. Therefore, it is necessary to develop a safe construction platform for water conservancy construction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a safe construction platform for water conservancy construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safe construction platform for water conservancy construction, including a base, a lifting mechanism on the top of the base, a lifting platform on the top of the lifting mechanism, a limit mechanism inside the lifting platform, and a protective mechanism on the top of the lifting platform.

[0006] Preferably, the limiting mechanism includes a rotating shaft rotatably mounted inside the lifting platform. A coil spring is fixedly mounted on the outside of the rotating shaft. A rectangular block is fixedly mounted on the bottom of the lifting platform. A take-up reel is fixedly mounted on the top of the rotating shaft. A pull rope is provided on the outside of the take-up reel. A fixing block is fixedly mounted on the end of the pull rope away from the take-up reel. A strap is fixedly mounted inside the fixing block. A ratchet is fixedly mounted on the outside of the rotating shaft. A pawl is rotatably mounted inside the lifting platform. A spring is fixedly mounted on the outside of the pawl. A positioning plate is slidably mounted up and down inside the lifting platform. A threaded rod is rotatably mounted inside the positioning plate. A limiting block is fixedly mounted on the top of the positioning plate. Under the action of the limiting block, the positioning plate descends and presses the ratchet, so that the rotating shaft and the take-up reel no longer rotate.

[0007] Preferably, the pull rope is movably installed inside the limiting block, the threaded rod is threadedly installed inside the lifting platform, the positioning plate is in contact with the ratchet, and the positioning plate descends under the action of the limiting block to press the ratchet tightly, so that the ratchet can no longer rotate.

[0008] Preferably, the end of the spring away from the pawl is fixedly installed to the lifting platform, the ratchet engages with the pawl, and the end of the coil spring away from the rotating shaft is fixedly installed to the rectangular block. This allows the coil spring to rewind and rotate the rotating shaft when the pawl is not engaged with the ratchet, so that the pull rope is stored outside the take-up reel for easy use next time.

[0009] Preferably, the protective mechanism includes a fence, which is fixedly installed on the top of the lifting platform. A limit plate is fixedly installed on the inner side of the fence. A functional block one is fixedly installed on the front of the fence. A rotating door is rotatably installed inside the fence. A functional block two is fixedly installed on the front of the rotating door. A pin is inserted into the interior of the functional block two so that the rotating door can be rotated to determine its position.

[0010] Preferably, the pin is inserted into the interior of functional block one to fix the position of the revolving door.

[0011] Preferably, the limiting plate contacts the revolving door to limit the rotation position of the revolving door.

[0012] Compared with the prior art, this utility model provides a safe construction platform for water conservancy construction, which has the following beneficial effects:

[0013] 1. This safety construction platform for water conservancy construction protects operators by closing the rotating door and inserting the latch into the interior of functional blocks one and two, so that the fence and the rotating door cooperate to form a U-shaped protective ring.

[0014] 2. Based on this, the present invention, by attaching the strap to the waist, allows the operator to move from the top of the lifting platform to the edge of the platform but not to the fence. The spring drives the pawl to engage with the outside of the ratchet, thus fixing the length of the pull rope. The rotating threaded rod positioning plate descends and presses the ratchet, so that the take-up reel stops rotating. This ensures that when the device shakes, the operator will not fall or even drop due to the pull of the pull rope, thus further protecting the operator.

[0015] 3. Based on this, when the limiting mechanism suddenly malfunctions, the protective mechanism can provide final protection for the operator. When the pawl is no longer engaged with the ratchet, the coil spring drives the rotating shaft to rotate, so that the pull rope is stored outside the take-up reel for easy use next time.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1:

[0026] Please see Figure 1-4This utility model provides a technical solution: a safe construction platform for water conservancy construction, including a base 1, a lifting mechanism 2 on the top of the base 1, a lifting platform 3 on the top of the lifting mechanism 2, a limit mechanism 4 inside the lifting platform 3, and a protective mechanism 5 on the top of the lifting platform 3.

[0027] Furthermore, the limiting mechanism 4 includes a rotating shaft 41, which is rotatably installed inside the lifting platform 3. A coil spring 42 is fixedly installed on the outside of the rotating shaft 41. A rectangular block 43 is fixedly installed at the bottom of the lifting platform 3. A take-up reel 44 is fixedly installed at the top of the rotating shaft 41. A pull rope 45 is provided on the outside of the take-up reel 44. A fixing block 46 is fixedly installed at the end of the pull rope 45 away from the take-up reel 44. A strap 47 is fixedly installed inside the fixing block 46. A ratchet 48 is fixedly installed on the outside of the rotating shaft 41. A pawl 49 is rotatably installed inside the lifting platform 3. A spring 410 is fixedly installed on the outside of the pawl 49. A positioning plate 411 is slidably installed up and down inside the lifting platform 3. A threaded rod 412 is rotatably installed inside the positioning plate 411. A limiting block 413 is fixedly installed at the top of the positioning plate 411. The positioning plate 411 descends under the action of the limiting block 413 and presses the ratchet 48, so that the rotating shaft 41 and the take-up reel 44 no longer rotate.

[0028] Furthermore, the pull rope 45 is movably installed inside the limit block 413, the threaded rod 412 is threadedly installed inside the lifting platform 3, the positioning plate 411 contacts the ratchet 48, and the positioning plate 411 descends under the action of the limit block 413 to press the ratchet 48 tightly, so that the ratchet 48 can no longer rotate.

[0029] Furthermore, the end of the spring 410 away from the pawl 49 is fixedly installed to the lifting platform 3, the ratchet 48 engages with the pawl 49, and the end of the coil spring 42 away from the rotating shaft 41 is fixedly installed to the rectangular block 43. This allows the coil spring 42 to rewind and drive the rotating shaft 41 to rotate when the pawl 49 is not engaged with the ratchet 48, so that the pull rope 45 is stored outside the take-up reel 44 for easy use next time.

[0030] Example 2:

[0031] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the protective mechanism 5 includes a fence 51, which is fixedly installed on the top of the lifting platform 3. A limit plate 52 is fixedly installed on the inner side of the fence 51. A functional block 53 is fixedly installed on the front of the fence 51. A rotating door 54 is rotatably installed inside the fence 51. A functional block 55 is fixedly installed on the front of the rotating door 54. A pin 56 is inserted into the interior of the functional block 55, so that the rotating door 54 can be rotated to determine its position.

[0032] Furthermore, the latch 56 is inserted into the interior of the functional block 53, thereby fixing the position of the revolving door 54.

[0033] Furthermore, the limiting plate 52 contacts the revolving door 54 to limit the rotation position of the revolving door 54.

[0034] In actual operation, when this device is in use, the upper latch 56 disengages from functional block 1 53 and functional block 2 55, opening the rotating door 54. The operator stands on top of the lifting platform 3, then closes the rotating door 54 and re-inserts the latch 56, causing the guardrail 51 and the rotating door 54 to cooperate to form a loop protective ring, protecting the operator. The strap 47 is then tied around the waist, and the operator moves on top of the lifting platform 3. At this time, the fixing block 46 drives the pull rope 45 to pull, causing... The take-up reel 44 rotates clockwise, causing the shaft 41 to rotate. Initially, the spring 410 is in a stretched state, and the spring 410 drives the pawl 49 to engage with the outside of the ratchet 48. At this time, the pawl 49 will not jam the ratchet 48. The rotation of the shaft 41 drives the coil spring 42 to rewind. When the person moves to the edge of the lifting platform 3 but does not touch the fence 51, the person stops moving. At this time, the coil spring 42 has a tendency to drive the shaft 41 to rotate back. However, the spring 410 drives the pawl 49 to engage with the ratchet. The external position of 48 fixes the length of the pull rope 45. The operator then moves to a position close to the take-up reel 44 and rotates the threaded rod 412, which is threaded inside the lifting platform 3. This causes the positioning plate 411 to descend under the action of the limit block 413, pressing the ratchet 48 tightly, preventing the ratchet 48 from rotating. Consequently, the shaft 41 and the take-up reel 44 stop rotating, preventing the pull rope 45 from stretching further when the operator walks beyond its maximum distance. This prevents the operator from falling when the device shakes, further protecting the operator. If the limit mechanism 4 malfunctions, the protective mechanism 5 can provide final protection for the operator. After use, the strap 47 is removed from the waist, and the pawl 49 is pulled to disengage from the ratchet 48. At this time, the coil spring 42 rewinds, causing the shaft 41 to rotate, allowing the pull rope 45 to be stored outside the take-up reel 44 for easy access next time.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
